[0003] Japanese Patent Application Laid-Open No. 2002-24787

[0004] However, there is room for improvement in identifying the type of cartridge when inserting the cartridge and in facilitating insertion and removal.

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cartridge and an information processing device that can identify the type of cartridge and facilitate insertion and removal.

[0006] In order to solve the above problems, the present invention employs the following configuration.

[0007] (First Configuration) The first configuration of this embodiment is a cartridge that is insertable into and removable from a first slot provided in a first game machine and a second slot provided in a second game machine in a first direction. The cartridge includes a housing and terminals that are electrically connectable to the first game machine terminals provided in the first slot and the second game machine terminals provided in the second slot. The cartridge is inserted into the first slot and the second slot from one end in the first direction. The housing includes a first notch that is provided at one end in a second direction perpendicular to the first direction and extends from the one end in the first direction to the other side opposite the one end. The first notch includes a first portion that is from an end of the housing closest to the one end in the second direction and has a length in the second direction that is a first width, and a second portion that is connected to the one side of the first portion in the first direction and extends to the end of the housing on the one side in the first direction, the second portion having a length in the second direction that is longer than the first width.

[0008] According to the above, it is possible to provide a cartridge that can be inserted into a first game machine and a second game machine. A first notch extending from one end of the cartridge in the first direction to the other end in the first direction is provided at one end of the cartridge. This first notch makes it easier to insert the cartridge into the first slot or the second slot. Furthermore, the second portion of the first notch is configured to be wider than the first portion. This ensures the strength of the housing, and when the cartridge is placed in the slot, a space can be formed in the second portion of the first notch inside the slot. For example, a terminal for identifying the cartridge can be placed in this space.

[0009] (Second configuration) In the second configuration, the terminal in the first configuration may be exposed from the housing, and the other end of the terminal exposed from the housing in the first direction may be located on the other side in the first direction than the second portion of the first cutout.

[0010] According to the above, the length of the second portion of the first cutout in the first direction can be shortened, and the strength of the housing can be ensured while providing the first cutout having the second width.

[0011] (Third configuration) In a third configuration, in the first or second configuration, the other end of the first notch in the first direction may be located on the other side in the first direction than the other end of the terminal in the first direction.

[0012] According to the above, the first cutout can be made longer in the first direction, and can function as a guide when inserting the cartridge into the first slot or the second slot.

[0013] (Fourth configuration) In a fourth configuration, in any of the first to third configurations, the end portion on one side in the first direction of the first notch may be positioned on the one side in the first direction of the end portion on one side in the first direction of the terminal.

[0014] According to the above, the first notch can be extended beyond one end of the terminal in the first direction, making it easier to insert the cartridge into the first slot or the second slot. Also, for example, if a terminal for identifying the cartridge is located deep within the first slot, when the cartridge is inserted into the first slot, the terminal can be accommodated in the space formed by the second portion of the first notch.

[0015] (Fifth Configuration) In a fifth configuration, in any one of the first to fourth configurations, the housing may further include a second notch provided at an end on the other side opposite the end on the one side in the second direction, and extending from the end on the one side of the cartridge in the first direction toward the other side in the first direction. The end on the other side of the second notch in the first direction may be located on the one side in the first direction with respect to the end on the one side of the second portion of the first notch in the first direction.

[0016] According to the above, the second notch can be provided on the opposite side in the second direction.

[0017] (Sixth Configuration) In a sixth configuration, in any one of the first to fifth configurations, the first portion of the first cutout may have a constant width in the second direction. The second portion of the first cutout may have a third portion having a constant width in the second direction and a fourth portion located on the other side of the third portion in the first direction, the fourth portion having a width in the second direction that narrows toward the first portion.

[0018] According to the above, the width of the first portion of the first cutout is constant, which makes it easier to insert the cartridge into the first slot or the second slot. Also, if the entire second portion of the first cutout is made up of the fourth portion, the cartridge will be more likely to tilt when inserted into the slot. However, by making the portion close to one side in the first direction the third portion, which has a constant width, it is easier to insert the cartridge straight.

[0019] (Seventh Configuration) In the seventh configuration, in any one of the first to fifth configurations, the width of the second portion in the second direction may be configured to become narrower toward the first portion in the first direction.

[0020] According to the above, for example, if the first part of the first notch has a constant first width and the second part has a constant second width, the boundary between the first part and the second part will be at a right angle, which could make the housing more susceptible to damage; however, with the above configuration, it is possible to make the housing less susceptible to damage.

[0021] (Eighth Configuration) In an eighth configuration, in any one of the first to seventh configurations, the terminals may include a first terminal arranged at a position closest to an end of the housing on the one side in the second direction, and a second terminal arranged adjacent to the first terminal in the second direction. In the first direction, the end of the first terminal on the one side in the first direction may be located on the other side in the first direction with respect to the end of the second terminal on the one side in the first direction.

[0022] According to the above, by making the length of the first terminal closest to one end in the second direction shorter than that of the second terminal, even when a first notch is provided, it is possible to make it less likely that the first terminal will be affected by the impact of the fall, for example, when the cartridge is dropped.

[0023] (Ninth configuration) In the ninth configuration, in any of the first to eighth configurations, the length of the second portion of the first cutout in the first direction may be shorter than the length of the first portion of the first cutout in the first direction.

[0024] According to the above, the first portion of the first cutout is long and the second portion is short, which allows the cartridge to be easily inserted into the first slot or the second slot using the first portion as a guide, and also ensures the strength of the housing.

[0025] (Tenth configuration) In the tenth configuration, in any of the first to ninth configurations, the first notch may be recessed from one end of the housing in the second direction to the other side in the second direction, and may be recessed from the back or front surface of the housing in a third direction perpendicular to the first and second directions.

[0026] According to the above, the notch can be formed while ensuring the strength of the housing. Furthermore, compared to, for example, a case in which the notch has an inverted C-shape cut only from the side, it is possible to make it easier to insert the cartridge.

[0027] (Eleventh Configuration) In an eleventh configuration, in any one of the first to tenth configurations, the second portion of the first cutout may have a substantially L-shape when viewed from the bottom of the cartridge.

[0028] According to the above, the notch can be formed while ensuring the strength of the housing.

[0029] (Twelfth Configuration) In the twelfth configuration, in any of the first to eleventh configurations, the second portion of the first cutout may be positioned so as to overlap with a predetermined terminal provided in the first slot when the cartridge is accommodated in the first slot.

[0030] According to the above, a specified terminal can be placed in the first slot, and even when a cartridge is housed in the first slot, the second part of the first notch can prevent contact with the specified terminal.

[0031] (Thirteenth Configuration) In a thirteenth configuration, in the twelfth configuration, the predetermined terminal may be a terminal for identifying the type of cartridge.

[0032] According to the above, when the cartridge is accommodated in the first slot, a predetermined terminal for identifying the type of cartridge can be accommodated in the second portion of the first cutout.

[0033] (14th configuration) In the 14th configuration, in any of the 1st to 13th configurations, the first portion of the first cutout has a substantially L-shape when viewed from the bottom of the cartridge, and may come into contact with guide portions provided on inner walls of the first slot and the second slot when the cartridge is inserted into the first slot and the second slot.

[0034] According to the above, the cartridge can be easily inserted into the first slot and the second slot.

[0035] (15th Configuration) The 15th configuration is an information processing device that is a generation later than the second information processing device. The information processing device includes a first slot. The first slot is capable of accepting a second cartridge, the second cartridge being insertable into the second slot of the second information processing device in a first direction and having a housing, and a first cartridge, the first cartridge being insertable into the second slot and having a housing shaped with a notch for the second cartridge. The information processing device includes: a plurality of first terminals arranged in a second direction perpendicular to the first direction, the first terminals being electrically connected to a plurality of terminals of the first cartridge inserted into the first slot and a plurality of terminals of the second cartridge inserted into the first slot; a switch provided in a position corresponding to the notch in the housing of the first cartridge accommodated in the first slot, the switch coming into contact with a portion of the housing of the second cartridge when the second cartridge is accommodated; and a circuit for determining whether the switch is on or off. The switch is provided at one end of the first slot in the second direction and protrudes from the one end toward the other side opposite the one side in the second direction.

[0036] Based on the above, it is possible to provide an information processing device into which a first cartridge and a second cartridge for a second information processing device of a previous generation can be inserted.

[0037] (16th Configuration) In the 16th configuration, in the 15th configuration, the second slot of the second information processing device does not need to be provided with the switch.

[0038] Based on the above, it is possible to provide a switch in an information processing device that is a generation later than the second information processing device.

[0039] (17th Configuration) In the 17th configuration, in the 15th or 16th configuration, the switch may be a second terminal that identifies the type of cartridge connected to the first slot.

[0040] Based on the above, the type of the connected cartridge can be identified by determining the state of the switch.

[0041] (18th configuration) In the 18th configuration, in the 17th configuration, the second terminal may have a first portion extending in the first direction, and a second portion connected to the one end of the first portion in the first direction and extending from the one end of the first slot in the second direction toward the other side in the second direction at an obtuse angle to the first direction.

[0042] According to the above, the second terminal has a first portion extending in a first direction and a second portion extending from the end on the one end side in the second direction toward the other end, and the first portion and the second portion form an obtuse angle, which makes it possible to easily insert and remove the cartridge.

[0043] (19th configuration) In the 19th configuration, in the 18th configuration, the second terminal may have a third portion extending from an end of the second portion on one side in the first direction to the one side in both the first direction and the second direction.

[0044] According to the above, the second terminal has a shape that is bent midway to one side in the second direction, which makes it possible to easily insert and remove the cartridge.

[0045] (Twentieth Configuration) A twentieth configuration of this embodiment is a cartridge that can be inserted into a first slot provided in a first game machine and a second slot provided in a second game machine in a first direction from one side in the first direction. The cartridge includes a housing and terminals that are exposed from a front surface of the housing and are electrically connectable to the first game machine terminals provided in the first slot and the second game machine terminals provided in the second slot. The housing has a recessed portion that is provided at an end on one side in a second direction perpendicular to the first direction and is recessed toward the back surface and in the second direction, such that a portion of the end surface facing the one side in the second direction is located further on the other side opposite the one side in the second direction than a portion on the other side.

[0046] According to the present invention, it is possible to provide a cartridge that can be inserted into a first game machine and a second game machine.

[0048] (Appearance of Cartridge 1) The cartridge 1 of this embodiment will now be described with reference to the drawings. The cartridge 1 is inserted into a slot of a game device (described later) and connected to the game device. The cartridge 1 stores a game program that enables execution of a predetermined game (for example, any game such as a racing game, role-playing game, shooting game, fighting game, rhythm game, etc.). The game device reads the game program stored in the cartridge 1 and executes the game program.

[0049] First, a description will be given of the appearance of the cartridge 1. Fig. 1 is a six-view diagram showing the appearance of the cartridge 1 of this embodiment.

[0050] 1(a) is a front view of the cartridge 1, FIG. 1(b) is a left side view of the cartridge 1, FIG. 1(c) is a right side view of the cartridge 1, FIG. 1(d) is a top view of the cartridge 1, FIG. 1(e) is a bottom view of the cartridge 1, and FIG. 1(f) is a rear view of the cartridge 1.

[0051] As shown in FIG. 1 , the cartridge 1 is formed of a front housing 2 and a rear housing 3. A substrate 40 having a plurality of terminals T is housed within the housing composed of the front housing 2 and the rear housing 3. The front housing 2 and the rear housing 3 are formed, for example, from synthetic resin and are joined by welding. Any material may be used for the front housing 2 and the rear housing 3. The front housing 2 and the rear housing 3 may be fixed by any method, such as fitting a claw and a hole or screwing. The housing of the cartridge 1 does not necessarily have to be composed of the front housing 2 and the rear housing 3, and may be composed of, for example, three or more housings. The housing of the cartridge 1 may also be composed of a single housing in which the front housing 2 and the rear housing 3 are substantially integrated.

[0052] Here, the direction in which the cartridge 1 is inserted is the negative y-axis direction, the direction perpendicular to the y-axis and pointing to the right when the front housing 2 is viewed from the front is the positive x-axis direction, and the direction perpendicular to the y-axis and x-axis and pointing from the front housing 2 to the rear housing 3 is the positive z-axis direction. The x-axis direction is also referred to as the rightward direction, and the y-axis direction is also referred to as the upward direction. The direction in which the surface on which the terminals T are provided is viewed from the front. In the following, for example, when referring to the "positive x-axis direction," the word "positive" will be omitted and it will be written as the "x-axis direction." The same applies to the y-axis and z-axis directions.

[0053] 1A, the front housing 2 is provided with five openings 23 for exposing a plurality of terminals T provided on the substrate 40. Specifically, the openings 23 are formed so as to extend in the y-axis direction from the bottom end of the cartridge 1 (the bottom end in FIG. 1A, also referred to as the tip).

[0054] A separator 24, which is a housing extending between the terminals, is provided between each opening 23. The separator 24 is a part of the front housing 2.

[0055] Furthermore, right-side cutouts (21 and 22) are formed in the right end (end in the x-axis direction) of the front housing 2, extending from the rightmost end of the housing in the negative x-axis direction. The right-side cutout has an upper portion 21 and a lower portion 22. Hereinafter, the upper portion 21 of the right-side cutout may be referred to as the "right-side cutout 21," and the lower portion 22 of the right-side cutout may be referred to as the "right-side cutout 22." The right-side cutouts 21 and 22 are recessed from the right side surface of the cartridge 1 in the negative x-axis direction and recessed from the front surface of the cartridge 1 in the z-axis direction. Specifically, as shown in (d) and (e) of FIG. 1 , the right-side cutouts 21 and 22 are formed by cutting out corners that are the ends of the front housing 2 in the x-axis direction and the negative z-axis direction, and have a generally L-shaped shape when viewed from the bottom or top. The right-side cutout 21 is formed so as to extend in the negative y-axis direction from near the top end of the cartridge 1 (the top end of the cartridge in FIG. 1( a)). The right-side cutout 21 may be formed from the top end of the cartridge 1, or may be formed from a position below the top end of the cartridge 1 as shown in FIG. 1. The length of the right-side cutout 21 in the y-axis direction is longer than the length of the right-side cutout 22 in the y-axis direction. The right-side cutout 21 functions as a rail for sliding the cartridge 1 when the cartridge 1 is inserted into a slot of a new game device 50 or an old game device 70 (described below). The right-side cutouts 21 and 22 do not have to be formed strictly parallel to the negative y-axis direction (the direction of insertion into the slot), and may be formed so as to extend in an oblique direction that includes a negative y-axis component (for example, in the negative y-axis and z-axis directions, or the negative y-axis and negative x-axis directions).

[0056] The right-side notch 22 extends from the bottom end of the cartridge 1 and is formed so as to connect to the right-side notch 21. The right-side notch 22 may not be formed from the bottom end of the cartridge 1, but may be formed from a position above the bottom end of the cartridge 1 (for example, a position between the bottom end of the cartridge 1 and the first position P_Y1 in FIG. 2 ).

[0057] Fig. 2 is a front view of the cartridge 1, showing an example of the size of the cartridge 1. Fig. 3 is a bottom view of the cartridge 1, showing an example of the size of the cartridge 1.

[0058] 2, the width (length in the x-axis direction) of the cartridge 1 is X0, which is set to, for example, approximately 20 mm to 22 mm, and the length (length in the y-axis direction) of the cartridge 1 is Y0, which is set to, for example, approximately 30 mm to 32 mm.

[0059] As shown in FIG. 2 , a plurality of terminals T are exposed from each of five openings 23 provided on the front surface of the cartridge 1. The plurality of terminals T include a plurality of short terminals arranged in the upper region, a plurality of short terminals arranged in the lower region, and a plurality of long terminals spanning the upper and lower regions. The positions of the upper ends of the plurality of short terminals arranged in the upper region and the long terminals are the same in the Y-axis direction. The positions of the lower ends of the plurality of short terminals arranged in the lower region and the long terminals are different in the Y-axis direction. Details of each terminal will be described later.

[0060] As shown in FIG. 2, the right-side cutout 21 has a constant width X1 (length X1 in the x-axis direction). The width of the right-side cutout 21 is the length X1 from the rightmost end of the housing in the negative x-axis direction. For example, the width X1 of the right-side cutout 21 may be 0.5 mm to 1.0 mm. Note that the four corners of the cartridge 1 are rounded, and the width of the right-side cutout 21 is not constant at the upper end, but narrows as it approaches the upper end.

[0061] The right-side cutout 22 is also formed in an R-shape from the bottom end of the cartridge to a first position P_Y1 in the y-axis direction (a position Y1 from the bottom end), and the width (length in the x-axis direction) of the right-side cutout 22 at this portion narrows toward the bottom end. The width of the right-side cutout 22 is a constant maximum width X2 from the first position P_Y1 in the y-axis direction to a second position P_Y2 (a position Y2 from the bottom end). The maximum width of the right-side cutout 22 is from the rightmost end of the housing to the length X2 in the negative x-axis direction. The right-side cutout 22 tapers from the second position P_Y2 to a third position P_Y3 (a position Y3 from the bottom end), and the third position P_Y3 is the upper end of the right-side cutout 22. The maximum width X2 of the right-side cutout 22 is wider than the width X1 of the right-side cutout 21. For example, the maximum width X2 of the right-side cutout 22 may be 1.5 mm to 2.0 mm. The length of the tapered portion in the Y-axis direction (Y3-Y2) may be, for example, 0.8 to 1 mm. The left end of the right-side cutout 22 extends linearly from the bottom end of the right-side cutout 22 to a second position P_Y2 in the y-axis direction. The length from the bottom end to the second position P_Y2 may be, for example, 3 mm to 4 mm. Furthermore, the left end of the right-side cutout 22 is formed so as to have an angle θ with respect to the y-axis from the second position P_Y2 to a third position P_Y3 in the y-axis direction. For example, θ may be 135 degrees.

[0062] In this way, the right-side cutout 22 has a tapered portion where the width narrows (a portion from the second position P_Y2 to the third position P_Y3) and a portion where the width is constant (a portion from the first position P_Y1 to the second position P_Y2). This makes it possible to ensure the strength of the housing of the cartridge 1 while providing a right-side cutout 22 with a wider width. Furthermore, by shortening the length of the wider right-side cutout 22 in the y-axis direction, the strength of the housing can be ensured.

[0063] As shown in FIG. 2 , the upper ends of the terminals T are located above the upper end of the right-side cutout 22. This ensures the strength of the housing that protects the terminals T. The lower end of the right-side cutout 22 is located below the lower ends of the terminals T. The upper end of the right-side cutout 21 is located above the upper ends of the terminals T. The lower end of the right-side cutout 21 extends to near the lower ends of the short terminals and long terminals arranged in the lower region. Specifically, the right-side cutout 21 extends below the center in the y-axis direction of the short terminals arranged in the lower region. This allows the right-side cutout 21 to function as a rail, allowing the cartridge 1 to be inserted straight into the slot of the game device. This reduces the likelihood of misalignment occurring in the connection between the cartridge terminals and the slot terminals. In addition, a right notch 22 is provided at the bottom end of the cartridge 1, making it easy to insert the cartridge 1 into the slot, and a right notch 21 is provided in continuation with the right notch 22, making it possible to smoothly guide the cartridge 1 in the insertion direction.

[0064] 3, the thickness Z0 (length in the z-axis direction) of the cartridge 1 may be, for example, approximately 2.5 mm to 3.0 mm. The depth Z1 (length in the z-axis direction) of the right-side cutouts 21 and 22 may be, for example, approximately 0.8 mm to 1.0 mm. The depth Z1 of the right-side cutouts 21 and 22 is smaller than half the thickness Z0 of the cartridge 1. The depth Z1 of the right-side cutouts 21 and 22 is also smaller than half the thickness Z2 of the front housing 2. Therefore, even if the right-side cutouts 21 and 22 are provided, the strength of the housing can be sufficiently maintained.

[0065] As shown in FIG. 2 , the width of the housing of the cartridge 1 (referred to as housing 27 in the figure) located between the rightmost terminal of the multiple terminals T and the right-side notch 22 is wider than the width X4 of the housing (separator 24) located between the multiple terminals. Specifically, the width X3 of the housing 27 corresponding to the portion of the right-side notch 22 from the bottom end to the second position P_Y2 is wider than the width X4. The width of the housing 27 corresponding to the portion of the right-side notch 22 from the second position P_Y2 to the third position P_Y3 is wider than the widths X3 and X4. Therefore, when the right-side notch 22 is located at the bottom end of the front housing 2 and the end in the x-axis direction, setting the width of the housing 27 corresponding to the right-side notch 22 to be equal to or greater than the width X4 can maintain the strength of the housing and prevent damage to the housing, for example, in the event of a drop. For example, the width X3 may be approximately 0.9 mm, and the width X4 may be approximately 0.85 mm. Note that the widths X3 and X4 may be the same. Furthermore, the width X3 may be narrower than the width X4.

[0066] Furthermore, the bottom end of the rightmost terminal of the multiple terminals T (the terminal closest to the right notch 22) is located higher than the bottom ends of the adjacent terminals. Terminals close to the notch are more susceptible to shock when the cartridge 1 is dropped, but by locating the bottom end of the terminal closest to the notch higher than the bottom ends of the adjacent terminals, it is possible to reduce the impact on the rightmost terminal when the cartridge 1 is dropped.

[0067] As shown in FIG. 1 , the cartridge 1 has left-side cutouts 25 and 26. The left-side cutouts 25 and 26 are formed at the left end (the end in the negative x-axis direction) and the end in the negative z-axis direction of the front housing 2. The left-side cutout 25 is formed further in the y-axis direction than the left-side cutout 26. The lower end of the left-side cutout 25 is located higher than the upper end of the right-side cutout 22. The left-side cutout 26 is also formed in the y-axis direction from the lower end of the cartridge 1. The upper end of the left-side cutout 26 is located lower than the upper end of the right-side cutout 22. The left-side cutouts 25 and 26 are used to secure the cartridge 1 at a predetermined position in the depth direction of the slot of the game device. Specifically, when the cartridge 1 is inserted into the slot of the game device, a locking portion 511 (see FIG. 27 ) provided on the left side surface of the slot engages with the left-side cutout 25. A member 510 that interlocks with a locking portion 511 is provided at the back of the slot, and when the cartridge 1 is pushed further inward, the left-side notch 26 acts on the member 510, moving the member 510 and the locking portion 511 in the back direction. The member 510 and the locking portion 511 are biased in the y-axis direction by a biasing member (not shown), and are locked when moved to a predetermined position in the back direction. This secures the cartridge 1 in a predetermined position at the back of the slot of the game device. When the cartridge 1 is pushed further inward while fixed in the predetermined position, the lock between the member 510 and the locking portion 511 is released, and the cartridge 1 is pushed out in the y-axis direction (removal direction).

[0068] Next, the front housing 2 and the rear housing 3 will be described. Fig. 4 is a six-view diagram showing the appearance of the front housing 2. Fig. 4(a) is a front view of the front housing 2, Fig. 4(b) is a left side view of the front housing 2, Fig. 4(c) is a right side view of the front housing 2, Fig. 4(d) is a top view of the front housing 2, Fig. 4(e) is a bottom view of the front housing 2, and Fig. 4(f) is a rear view of the front housing 2. The xyz coordinate system in Fig. 4 coincides with the xyz coordinate system in Fig. 1.

[0069] FIG. 5 is a six-view diagram showing the appearance of the rear housing 3. FIG. 5(a) is a front view of the rear housing 3. The xyz coordinate system in FIG. 5 coincides with the xyz coordinate system in FIG. 1. FIG. 5(a) is a diagram of the cartridge 1 as viewed from the rear. FIG. 5(b) is a left side view of the rear housing 3 and a diagram of the cartridge 1 as viewed from the right side. FIG. 5(c) is a right side view of the rear housing 3, FIG. 5(d) is a top view of the rear housing 3, and FIG. 5(e) is a bottom view of the rear housing 3. FIG. 5(f) is a rear view of the rear housing 3.

[0070] 6 is a cross-sectional view taken along line AA in Fig. 1. Fig. 7 is a cross-sectional view taken along line BB in Fig. 1.

[0071] The front housing 2 and the rear housing 3 are each molded using, for example, a mold. As shown in Fig. 5 , a rib 31 is provided on the rear surface of the rear housing 3 along the outer edge of the rear housing 3. The rib 31 is a welding margin. As shown in Figs. 6 and 7 , a substrate 40 is housed between the rear housing 3 and the front housing 2, and the rear housing 3 and the front housing 2 are combined so that they overlap, and the rib 31 of the rear housing 3 is welded to the front housing 2.

[0072] The ribs 31 are provided on the four sides of the rear surface of the rear housing 3, but not on the rounded corners. The ribs 31 may also be provided on the rounded corners of the rear surface of the rear housing 3, and the front housing 2 and the rear housing 3 may be welded together at the rounded corners.

[0073] 7, the center of the rib 31 is positioned so as to substantially coincide with the end of the right cutout 22 in the negative x-axis direction (the end closest to the center of the cartridge 1). When the right cutout 22 is viewed in a plan view perpendicular to the x-z plane, the center of the rib 31 is positioned further in the x-axis direction than the end of the right cutout 22 in the negative x-axis direction. The width of the rib 31 (length in the x-axis direction) may be shorter than the width of the right cutout 22 (length in the x-axis direction). The width of the rib 31 may also be shorter than the width of the right cutout 21 (length in the x-axis direction). For example, the width of the rib 31 may be 0.5 mm to 0.6 mm.

[0074] When the front housing 2 and the rear housing 3 are welded by the rib 31, the x-axis direction range of the welded portion includes the end of the right cutout 21 in the negative x-axis direction. In other words, when the welded portion and the right cutout 21 are viewed in a plan view perpendicular to the xy plane, at least a portion of the welded portion overlaps with at least a portion of the right cutout 21. This allows the front housing 2 and the rear housing 3 to be firmly connected together even if the right cutout 21 is provided in the front housing 2.

[0075] (Connection between cartridge 1 and game device) Next, a description will be given of the connection between the cartridge 1 and the game device. Figure 8 is a diagram for explaining the connection between the cartridge 1 and the new game device or the old game device.

[0076] As shown in FIG. 8 , cartridge 1 can be inserted into a first slot of the new game device 50 and can be electrically connected to a terminal provided in the first slot. The new game device 50 is a successor (next-generation model) to the old game device 70 and will be released after the old game device 70. The new game device 50 is a game device with higher performance than the old game device 70. For example, the new game device 50 has a CPU with higher processing power than the old game device 70. For example, the new game device 50 has a GPU with higher image processing power than the old game device 70. For example, the new game device 50 can read and generate images with higher resolution than the old game device 70 and display the images on the display. Cartridge 1 is detachably connected to the new game device 50. The new game device 50 reads the game program, image data, etc. stored in cartridge 1 and executes game processing.

[0077] The cartridge 1 can also be inserted into a second slot of the old game device 70, and can be electrically connected to a terminal provided in the second slot. The old game device 70 can, for example, read the game program stored in the cartridge 1 and execute game processing.

[0078] Furthermore, a cartridge 7 manufactured for the old game device 70 can be inserted into the second slot of the old game device 70. The cartridge 7 has a right-side notch 21 like the cartridge 1, but does not have a right-side notch 22. The old game device 70 can read the game program and the like from the cartridge 7 connected to the second slot and execute game processing.

[0079] The cartridge 7 can also be inserted into the first slot of the new game device 50. The new game device 50 can read the game program and the like from the cartridge 7 and execute game processing.

[0080] Here, the cartridge 1 having the right-side cutout 22 will be referred to as the "new cartridge 1." Furthermore, the cartridge 7 without the right-side cutout 22 will be referred to as the "old cartridge 7." Furthermore, when there is no particular distinction between the new cartridge 1 and the old cartridge 7, they will be referred to as the "cartridge." Furthermore, when there is no particular distinction between the new game device 50 and the old game device 70, they will be referred to as the "game device," and when there is no particular distinction between the first slot and the second slot, they will be referred to as the "slot."

[0081] In this way, the new cartridge 1 can be connected to both the new game device 50 and the old game device 70. Both the new game device 50 and the old game device 70 can read data stored in the new cartridge 1 and write data to the new cartridge 1. Furthermore, the old cartridge 7 can be connected to both the new game device 50 and the old game device 70. Both the new game device 50 and the old game device 70 can read data stored in the old cartridge 7 and write data to the old cartridge 7. As will be described in detail later, the new game device 50 has an identification terminal that distinguishes between the new cartridge 1 and the old cartridge 7, while the old game device 70 does not have such an identification terminal.

[0082] (Configuration of New Game Device and New Cartridge) Next, the configuration of the new game device 50 and the new cartridge 1 will be described.

[0083] Figure 9 is a diagram showing an example of the configuration of the new game device 50. As shown in Figure 9, the new game device 50 has a first slot 51. The new cartridge 1 or old cartridge 7 can be inserted into or removed from the first slot 51. A connector having multiple terminals P (P0 to P17) is provided inside the first slot 51. The multiple terminals P provided inside the first slot 51 are connected to multiple terminals T provided on the new cartridge 1. The multiple terminals P0 to P17 on the new game device 50 will be described in detail later.

[0084] The new game device 50 includes a switching unit 52, a switching unit 53, and a conversion unit 54. The new game device 50 also includes a SoC (System on a Chip) 55. The SoC 55 includes one or more processors and a memory. For example, the SoC 55 includes one or more CPUs (Central Processing Units). For example, the CPU of the SoC 55 has higher processing power than the CPU of the SoC 73 included in the old game device 70 (described later), and can execute instructions that the CPU of the SoC 73 cannot execute. The CPU of the SoC 55 executes application programs such as game applications. The SoC 55 also includes a GPU (Graphics Processing Unit) that performs image processing. The GPU of the SoC 55 has higher processing power than the GPU of the SoC 73 included in the old game device 70. Note that the new game device 50 may have a CPU and a GPU that are provided separately.

[0085] The switching unit 52 is electrically connected to the plurality of terminals P in the first slot 51. The switching unit 52 functions as a branching unit that branches signals from the plurality of terminals P to a first path or a bypass path. The bypass path branching from the switching unit 52 is connected to the conversion unit 53. The first path branching from the switching unit 52 is connected to the conversion unit 54, and the conversion unit 54 is further connected to the switching unit 53 via a second path. The bypass path branching from the switching unit 52 and the second path connected to the conversion unit 54 merge in the switching unit 53. The switching unit 53 is connected to the SoC 55. The switching unit 52 and the switching unit 53 switch between the first path and the bypass path based on a switching signal from the SoC 55. The switching unit 52, the switching unit 53, the conversion unit 54, the bypass path, the first path, and the second path may be configured by one or more integrated circuits.

[0086] In the bypass path between the switching unit 52 and the switching unit 53, signals conforming to a first standard are transmitted and received. The first standard may be, for example, eMMC (embedded Multi Media Card). The first standard may be any other standard or a proprietary standard. In addition, in the first path between the switching unit 52 and the conversion unit 54, signals conforming to a second standard are transmitted and received. The second standard may be, for example, a proprietary standard. The second standard may be any other standard.

[0087] The first standard and the second standard have different performances. For example, the first standard may have a faster data transmission speed than the second standard. Furthermore, the first standard may consume less power than the second standard.

[0088] Communication between the switching unit 53 and the conversion unit 54 is based on the first standard. Specifically, when data communication is performed using the first path, the conversion unit 54 converts a signal conforming to the second standard from the switching unit 52 into a signal conforming to the first standard and transmits it to the switching unit 53. The conversion unit 54 also converts a signal conforming to the first standard from the switching unit 53 into a signal conforming to the second standard and transmits it to the switching unit 52. Communication between the SoC 55 and the switching unit 53 is based on the first standard. The conversion unit 54 also encrypts and decrypts communication between the SoC 55 and the old cartridge 7. Specifically, the conversion unit 54 receives data from the SoC 55 via the switching unit 53 and encrypts the data. The encrypted data is transmitted to the old cartridge 7 via the switching unit 52. The conversion unit 54 also receives data from the old cartridge 7 and decrypts it. The decrypted data is transmitted to the SoC 55 via the switching unit 53.

[0089] Figure 10 is a diagram showing an example of the configuration of the new cartridge 1. As shown in Figure 10, the new cartridge 1 has a plurality of terminals T (T1 to T16). As will be described in detail later, when the new cartridge 1 is inserted into the first slot 51 of the new game device 50, the plurality of terminals T are connected to the plurality of terminals P provided in the first slot 51. Furthermore, when the new cartridge 1 is inserted into the second slot 71 of the old game device 70, the plurality of terminals T are connected to the plurality of terminals P provided in the second slot 71.

[0090] The new cartridge 1 also includes a storage medium 11 and a control unit 12. The storage medium 11 is provided with a first storage area and a second storage area. Data stored in the first storage area is encrypted in a first format, and data stored in the second storage area is encrypted in a second format different from the first format. The new game device 50 can decrypt data encrypted in the first format and data encrypted in the second format, and can read both data stored in the first storage area and data stored in the second storage area. On the other hand, the old game device 70 can decrypt data encrypted in the second format and can read data stored in the second storage area. The storage medium 11 stores application programs (e.g., game programs), image data (e.g., texture data), and the like. The storage medium 11 also stores metadata indicating the game title and ID, and the like. The data stored in the storage medium 11 will be described later.

[0091] The multiple terminals T are electrically connected to the control unit 12. Specifically, the multiple terminals T are connected to the control unit 12 by one path (signal line; bus). The control unit 12 is also connected to the storage medium 11 by one path (signal line; bus).

[0092] The control unit 12 and the storage medium 11 may be connected via two paths. Specifically, the control unit 12 and the storage medium 11 may be connected via a first path for transmitting signals based on the first standard and a second path for transmitting signals based on the second standard. Furthermore, the multiple terminals T and the control unit 12 may be connected via two paths. Specifically, the multiple terminals T and the control unit 12 may be connected via a third path for transmitting signals based on the first standard and a fourth path for transmitting signals based on the second standard.

[0093] The control unit 12 controls communication between the new cartridge 1 and the game device, and performs processing in response to read and write commands from the game device. The control unit 12 has the function of switching between the first standard and the second standard. When the new cartridge 1 is connected to the new game device 50, the control unit 12 controls signals conforming to the first standard, and when the new cartridge 1 is connected to the old game device 70, the control unit 12 controls signals conforming to the second standard. The control unit 12 will be described in detail below with reference to FIG. 11.

[0094] FIG. 11 is a diagram showing an example of the configuration of the control unit 12 of the new cartridge 1. As shown in FIG. 11, the control unit 12 has a CPU 120, a first standard circuit 121, a second standard circuit 122, a storage medium control unit 123, and a memory 124. Note that each of the units 121 to 124 shown in FIG. 11 may be configured on a single chip or multiple chips. For example, the control unit 12 may be configured as an SoC including the CPU 120, the first standard circuit 121, the second standard circuit 122, and the memory 124.

[0095] The CPU 120 controls the first standard circuit 121 , the second standard circuit 122 , and the storage medium control unit 123 .

[0096] The memory 124 is a non-volatile memory, and may be, for example, a read-only memory or a read / write memory. Normal firmware and compatible firmware are stored in the memory 124. Alternatively, the memory 124 may not be provided, and each firmware may be stored in the storage medium 11.

[0097] The firmware manages the storage area of ​​the storage medium 11 (reading, writing, security processing, etc.), manages communications with game devices, and manages security. The normal firmware is firmware for operating the new cartridge 1 in normal mode. The compatible firmware is firmware for operating the new cartridge 1 in compatible mode. In normal mode, communication based on a first standard is carried out between the new cartridge 1 and the new game device 59. In compatible mode, communication based on a second standard is carried out between the new cartridge 1 and the old game device 70.

[0098] Specifically, when the new cartridge 1 operates in normal mode, the CPU 120 issues an instruction to the first-standard circuit 121 to process a signal conforming to the first standard, and the first-standard circuit 121 processes the signal conforming to the first standard. For example, when information is written to the storage medium 11, the first-standard circuit 121 processes a signal conforming to the first standard received via terminal T and transmits information corresponding to the processing result to the storage medium control unit 123. The CPU 120 issues a write instruction to the storage medium control unit 123, and the storage medium control unit 123 writes the information to the storage medium 11 in response to the instruction. When information is read from the storage medium 11, the CPU 120 issues a read instruction to the storage medium control unit 123, and the storage medium control unit 123 reads the information from the storage medium 11 in response to the instruction. The read information is transmitted to the first-standard circuit 121, and the first-standard circuit 121 transmits a signal conforming to the first standard based on the information to terminal T.

[0099] Furthermore, when the new cartridge 1 operates in the compatible mode, the CPU 120 issues an instruction to the second-standard circuit 122 to process signals conforming to the second standard, and the second-standard circuit 122 processes the signals conforming to the second standard. When communication based on the second standard is performed between the new cartridge 1 and the game device, the processing flow is similar to that described above.

[0100] 11, the first standard circuit 121 and the storage medium control unit 123 are connected by a common signal line (common bus), and the second standard circuit 122 and the storage medium control unit 123 are connected by the common bus. Also, in Fig. 11, the first standard circuit 121 is connected to the connection point with the terminal T by a second common signal line (second common bus), and the second standard circuit 122 is connected to the connection point with the terminal T by the second common bus.

[0101] Therefore, when the new cartridge 1 communicates with the game device based on the first standard, a signal conforming to the first standard received at terminal T is input to the circuit for the first standard 121 via the second common bus, and information corresponding to the results of processing by the circuit for the first standard 121 is sent to the storage medium control unit 123 via the first common bus. This causes information to be written to the storage medium 11. The process is reversed when reading information from the storage medium 11. On the other hand, when the new cartridge 1 communicates with the game device based on the second standard, a signal conforming to the second standard received at terminal T is input to the circuit for the second standard 122 via the second common bus, and information corresponding to the results of processing by the circuit for the second standard 121 is sent to the storage medium control unit 123 via the first common bus.

[0102] In another embodiment, the first standard circuit 121 and the storage medium control unit 123 may be connected by a first bus, and the second standard circuit 122 and the storage medium control unit 123 may be connected by a second bus. Also, the first standard circuit 121 may be connected to the connection point with the terminal T by a third bus, and the second standard circuit 122 may be connected to the connection point with the terminal T by a fourth bus.

[0103] (Connection of new cartridge 1 to game device) Next, we will explain the operation of the new cartridge 1 and the new game device 50 when the new cartridge 1 is connected to the new game device 50. Figure 12 is a diagram for explaining the operation of the new game device 50 and the new cartridge 1 when the new cartridge 1 is connected to the new game device 50.

[0104] 12, when the new cartridge 1 is connected to the first slot 51 of the new game device 50, the new game device 50 operates in normal mode. In normal mode, the bypass path is enabled, and communication between the new game device 50 and the new cartridge 1 is carried out based on the first standard via the bypass path.

[0105] Specifically, when new cartridge 1 is connected to first slot 51, SoC 55 detects that new cartridge 1 has been connected based on the state of the terminals in first slot 51. By default, the bypass path is enabled, and based on a switching signal from SoC 55, switching units 52 and 53 switch from the bypass path to the first path. When SoC 55 detects new cartridge 1, it does not send a switching signal to switching units 52 and 53. Note that when SoC 55 detects that new cartridge 1 has been connected, it may send a switching signal to switching units 52 and 53 to switch to the bypass path. Based on this switching signal, switching units 52 and 53 may switch to the bypass path. As a result, communication between the new game device 50 and new cartridge 1 will be performed based on the first standard.

[0106] On the other hand, when the new cartridge 1 is connected to the first slot 51 of the new game device 50, it detects that it has been connected to the new game device 50 based on the state of the terminal T. When the control unit 12 detects that it has been connected to the new game device 50, it causes the new cartridge 1 to operate in normal mode. As a result, communication between the new cartridge 1 and the new game device 50 will be carried out based on the first standard.

[0107] When new cartridge 1 is connected to new game console 50, SoC 55 of new game console 70 can read data stored in the first memory area of ​​storage medium 11 and write data to the first memory area. SoC 55 of new game console 70 can also read data stored in the second memory area and write data to the second memory area.

[0108] Next, we will explain the operation of the new cartridge 1 when it is connected to the old game device 70. Figure 13 is a diagram for explaining the operation of the new cartridge 1 when it is connected to the old game device 70.

[0109] As shown in FIG. 13 , the old game device 70 has a second slot 71. The second slot 71 has the same shape and size as the first slot 51. A connector having a plurality of terminals P (P0 to P16) is provided inside the second slot 71. The plurality of terminals P0 to P16 provided inside the second slot 71 have the same functions as the plurality of terminals P0 to P16 provided inside the first slot 51 of the new game device 50. Furthermore, the positions of the terminals P0 to P16 of the second slot 71 within the second slot 71 are the same as the positions of the terminals P0 to P16 of the first slot 51 within the first slot 51.

[0110] The old game device 70 also includes a conversion unit 72 and an SoC 73. The SoC 73 includes a CPU and a GPU. The conversion unit 72 is electrically connected to multiple terminals P of the second slot 71 via a first path. Communication between the conversion unit 72 and the multiple terminals P is based on the second standard. The conversion unit 72 is also electrically connected to the SoC 73 via a second path. Communication between the conversion unit 72 and the SoC 73 is based on the first standard. Specifically, the conversion unit 72 converts signals conforming to the second standard from the multiple terminals P into signals conforming to the first standard and transmits them to the SoC 73. The conversion unit 72 also converts signals conforming to the first standard from the SoC 73 into signals conforming to the second standard and transmits them to the multiple terminals P. The conversion unit 72 also performs encryption / decryption processing, similar to the conversion unit 54. The old game device 70 does not include the bypass path that the new game device 50 includes. The conversion unit 72, the first path, and the second path may be configured by one or more integrated circuits.

[0111] When new cartridge 1 is connected to second slot 71, SoC 73 detects that a cartridge has been connected based on the state of the terminals in second slot 71. Old game device 70 is designed on the assumption that old cartridge 7 will be inserted. SoC 73 does not distinguish whether the connected cartridge is new cartridge 1 or old cartridge 7, but simply detects that a cartridge has been connected.

[0112] On the other hand, when the new cartridge 1 is connected to the second slot 71 of the old game device 70, it detects that it is connected to the old game device 70 based on the state of the terminal T. When the control unit 12 detects that it is connected to the old game device 70, it causes the new cartridge 1 to operate in compatibility mode. As a result, communication between the new cartridge 1 and the old game device 70 is performed based on the second standard.

[0113] When new cartridge 1 is connected to old game device 70, SoC 73 of old game device 70 can read data stored in the second memory area of ​​storage medium 11 and write data to the second memory area. However, SoC 73 of old game device 70 cannot read data stored in the first memory area or write data to the first memory area.

[0114] Next, we will explain the operation of the new game device 50 when the old cartridge 7 is connected to the new game device 50. Figure 14 is a diagram for explaining the operation of the new game device 50 when the old cartridge 7 is connected to the new game device 50.

[0115] 14, when an old cartridge 7 is connected to the first slot 51 of the new game device 50, the new game device 50 operates in compatibility mode. In compatibility mode, the first path is enabled (the bypass path is disabled), and communication between the new game device 50 and the old cartridge 7 is performed via the first path based on the second standard.

[0116] Specifically, when an old cartridge 7 is connected to the first slot 51, the SoC 55 detects that the old cartridge 7 has been connected based on the state of the terminals in the first slot 51. When the SoC 55 detects that an old cartridge 7 has been connected, it sends a switching signal to the switching units 52 and 53 to switch to the first path. Based on this switching signal, the switching units 52 and 53 switch to the first path. As a result, communication between the new game device 50 and the old cartridge 7 is performed based on the second standard.

[0117] The old cartridge 7 recognizes that it is connected to either the new game device 50 or the old game device 70, but does not recognize which game device it is connected to. The old cartridge 7 has multiple terminals T, just like the new cartridge 1. The old cartridge 7 also has a control unit 7a and a storage medium 7b. The control unit 7a does not have the function of switching between the first and second standards, as the control unit 12 does. When the old cartridge 7 is connected to the new game device 50 or the old game device 70, the control unit 7a controls signals conforming to the second standard.

[0118] As shown in Figures 9 to 14, both the SoC 55 of the new game console 50 and the SoC 73 of the old game console 70 process signals conforming to the first standard. Because the old cartridge 7 can only send and receive signals conforming to the second standard with the old game console 70, a converter 72 that converts signals conforming to the second standard into signals conforming to the first standard is provided in the old game console 70 between the SoC 73 of the old game console 70 and the old cartridge 7. On the other hand, because the new cartridge 1 can send and receive signals conforming to the first standard with the new game console 50, there is no need to provide a converter on the new game console 50 side for conversion to signals conforming to the first standard. However, in order to enable the old cartridge 7 to be connected to the new game console 50, it is necessary to enable signals conforming to the second standard to be sent and received from a slot in the new game console 50. For this reason, the new game device 50 is equipped with a conversion unit 54 that converts signals conforming to the second standard into signals conforming to the first standard, and with switching units 52 and 53 that switch between a first path that passes through the conversion unit 54 and a bypass path. The new cartridge 1 is also configured to be able to send and receive signals conforming to the second standard so that it can be connected to the old game device 70. When connected to the new game device 50, the new cartridge 1 sends and receives signals conforming to the first standard, and when connected to the old game device 70, it sends and receives signals conforming to the second standard.

[0119] 10, the control unit 12 and storage medium 11 of the new cartridge 1 may be connected using a storage medium interface standard (third standard). When data in the new cartridge 1 is read from the game device, the data from the storage medium 11 may be transmitted to the control unit 12 as a signal conforming to the third standard, and the control unit 12 may convert the signal into a signal conforming to the first or second standard. Alternatively, a converter may be provided between the control unit 12 and the storage medium 11, separate from the control unit 12, and the converter may convert between the third standard and the first or second standard. Similarly, in FIG. 14, the control unit 7a and storage medium 7b of the old cartridge 7 may be connected using the third standard. When data in the old cartridge 7 is read from the game device, the data from the storage medium 7b may be transmitted to the control unit 7a as a signal conforming to the third standard, and the control unit 7a may convert the signal into a signal conforming to the second standard.

[0120] Next, a description will be given of the data stored in the storage medium 11 of the new cartridge 1. The new cartridge 1 of this embodiment may be configured as a universal cartridge or as a dedicated cartridge.

[0121] Here, the universal cartridge and the dedicated cartridge are new cartridges 1 having the above-described external appearance and internal structure, and as described above, operate in a mode corresponding to the game device to which they are connected. The universal cartridge is a cartridge that can be substantially used on both the new game device 50 and the old game device 70, and contains a program that realizes substantially the same functions when connected to the new game device 50 and the old game device 70. For example, the universal cartridge stores a game program that can run a predetermined game when connected to both the new game device 50 and the old game device 70. On the other hand, the dedicated cartridge is a cartridge that can be used on the new game device 50 but cannot substantially be used on the old game device 70, and contains a program that realizes a predetermined function when connected to the new game device 50. When the dedicated cartridge is connected to the old game device 70, the old game device 70 does not realize the predetermined function. For example, the dedicated cartridge stores a game program that can run a predetermined game only when connected to the new game device 50, and when the dedicated cartridge is connected to the old game device 70, the old game device 70 cannot run the predetermined game.

[0122] 15 is a diagram showing an example of data stored in the storage medium 11 of the new cartridge 1 when the new cartridge 1 is configured as a shared cartridge. The storage medium 11 has a first storage area and a second storage area. Note that the first storage area and the second storage area may be provided on physically separate storage media. That is, the storage medium 11 may be composed of a first storage medium having the first storage area and a second storage medium having the second storage area. Furthermore, the first storage area and the second storage area may be provided in a single storage medium.

[0123] As shown in FIG. 15 , a first application program is stored in the first storage area. The first application program may include instructions that are executable by the SoC 55 of the new game device 50 but not executable by the SoC 73 of the old game device 70. For example, a first game program is stored as an example of the first application program. The first storage area also stores first image data and first metadata. The first game program is, for example, a game program that causes the new game device 50 to perform game processing for a predetermined game (e.g., a racing game, a role-playing game, a shooting game, a fighting game, etc.). The first image data is image data used in the predetermined game, such as character texture data and texture data representing the terrain of the virtual space. The first metadata is data indicating information about the predetermined game, such as data indicating the title of the predetermined game, an image representing the title, the game ID, the production date, the size of the storage area, etc.

[0124] The second storage area also stores a second application program. The second application program includes instructions executable by the SoC 73 of the old game device 70. For example, a second game program is stored as an example of the second application program. The second storage area also stores second image data and second metadata. The second game program is a game program for causing the old game device 70 to perform game processing for the predetermined game. The second image data is image data used in the predetermined game, such as character texture data and texture data representing the topography of the virtual space. The second metadata is data indicating information about the second game program, such as data indicating the title of the predetermined game, an image representing the title, the game ID, the production date, the size of the storage area, etc.

[0125] For example, when new cartridge 1 is connected to new game device 50, new game device 50 reads first metadata stored in the first storage area and displays information related to the first application program. When a user instructs execution of the first application program, new game device 50 reads the first application program from the first storage area based on the first standard and executes the read first application program. Furthermore, while the first application program is running, new game device 50 reads first image data from the first storage area based on the first standard and displays an image corresponding to the read first image data.

[0126] On the other hand, when the new cartridge 1 is connected to the old game device 70, the old game device 70 reads the second metadata stored in the second storage area and displays information related to the second application program. When the user instructs execution of the second application program, the old game device 70 reads the second application program from the second storage area based on the second standard and executes the read second application program. Furthermore, while the second application program is running, the old game device 70 reads second image data from the second storage area based on the second standard and displays an image corresponding to the read second image data.

[0127] The first application program may be a program that can provide the same functions as the second application program. Furthermore, the first application program may include all functions, content, etc. that can be executed by the second application program, and may also include other functions, content, etc. that are not included in the second application program. For example, the first application program and the second application program may both be game programs for playing a racing game, and the first application program may be a racing game program that includes all courses that can be executed by the second application program and courses that cannot be executed by the second application program.

[0128] Furthermore, for example, the first application program may be capable of running a game with more players than the second application program, may have a greater variety of items than the second application program, may have a greater number and types of items that player characters can hold than the second application program, or may have a greater number and types of characters than the second application program.

[0129] The first image data may be the same as the second image data, but may have a higher resolution than the second image data. For example, the first image data may include a texture image of a predetermined character having a first resolution, and the second image data may include a texture image of the predetermined character having a second resolution lower than the first resolution. The first image data may also include image data that is completely different from the second image data.

[0130] FIG. 16 is a diagram showing another example of data stored in the storage medium 11 of the new cartridge 1 when the new cartridge 1 is configured as a universal cartridge.

[0131] As shown in FIG. 16 , the first storage area stores a dedicated program, dedicated image data, and dedicated metadata. The dedicated program is a program that can be executed by the new game device 50 but cannot be executed by the old game device 70. The dedicated program may be, for example, an extension program for executing an extended scene or an extended function that can be executed only by the new game device 50 in a specific game. The dedicated image data is image data that can be displayed (processed) by the new game device 50 but cannot be displayed (processed) by the old game device 70. The dedicated metadata is data that can be read by the new game device 50. The dedicated metadata is, for example, metadata related to the dedicated program (for example, data indicating the name and information of the extended function).

[0132] The second storage area also stores a common program, common image data, and common metadata. The common program is a program that can be executed by the new game device 50 and the old game device 70. The common program may be a game program for playing a predetermined game. The common image data is image data that can be displayed (processed) by the new game device 50 and the old game device 70. The common image data may be image data with a lower resolution than the dedicated image data. The common metadata is data that can be read by the new game device 50 and the old game device 70. The common metadata includes, for example, data indicating the title and ID of the game.

[0133] When a new cartridge 1 storing the data shown in Fig. 16 is connected to a new game device 50, the new game device 50 performs game processing for a predetermined game using a common program and common image data. For example, if a transition to an extended scene executable on the new game device 50 occurs during execution of the game processing, the new game device 50 performs game processing for the extended scene based on the dedicated program and dedicated image data stored in the first memory area. On the other hand, when a new cartridge 1 storing the data shown in Fig. 16 is connected to an old game device 70, the old game device 70 performs game processing for a predetermined game using a common program and common image data. The old game device 70 cannot execute the dedicated program stored in the first memory area, so the transition to the extended scene does not occur.

[0134] In this way, data exclusive to the new game device 50 is stored in the first memory area, and data shared by the new game device 50 and the old game device 70 is stored in the second memory area, and the new game device 50 can switch the data it reads depending on the conditions, thereby reducing the capacity of the storage medium 11.

[0135] FIG. 17 is a diagram showing an example of data stored in the storage medium 11 of the new cartridge 1 when the new cartridge 1 is configured as a dedicated cartridge.

[0136] As shown in FIG. 17 , a first storage area of ​​the storage medium 11 stores a first application program, first image data, and first metadata. The first application program is a game program for executing game processing of a predetermined game. The first image data is image data used during execution of the game processing, and may be, for example, character texture data. The first metadata is data representing the title of the predetermined game, etc. Meanwhile, a display program, second image data, and second metadata are stored in the second storage area. The display program is a program different from the first application program and does not execute the predetermined game. For example, the display program is a program for causing the old game device 70 to display information indicating that the predetermined game (a game that is executable by the new game device 50 and is indicated by the second metadata) cannot be executed on the old game device 70. The second image data is image data used to execute the display program. The second metadata is, for example, data representing the title of the predetermined game, etc.

[0137] Next, a description will be given of game images displayed when the new cartridge 1 is connected to a game device. Figure 18 shows an example of a game image when a universal cartridge is connected to a new game device 50 and a game program is being executed. Figure 19 shows an example of a game image when a universal cartridge is connected to an old game device 70 and a game program is being executed.

[0138] Here, the new cartridge 1 is configured as the common cartridge shown in Fig. 15 or 16. The common cartridge stores, for example, a game program for playing a predetermined racing game. As shown in Figs. 18 and 19, when the new cartridge 1 is connected to the new game device 50, the predetermined racing game is played on the new game device 50. Also, when the new cartridge 1 is connected to the old game device 70, the same predetermined racing game is played on the old game device 70. Note that when the new cartridge 1 is connected to the new game device 50, courses of a racing game that cannot be played on the old game device 70 may be playable on the new game device 50.

[0139] FIG. 20 shows an example of an image that is displayed when the new cartridge 1 is connected to the old game device 70 when the new cartridge 1 is configured as a dedicated cartridge.

[0140] Here, the first storage area of ​​the new cartridge 1 stores a game program capable of executing a predetermined racing game as a first application program, and the second storage area stores a display program. When such a new cartridge 1 is connected to an old game device 70, the old game device 70 executes the display program stored in the new cartridge 1. As shown in FIG. 20 , when the old game device 70 executes the display program, a display (a warning display or an error display) is displayed indicating that the predetermined game cannot be executed on the old game device 70. This display may include, for example, the title of the predetermined game or an image related to the predetermined game. On the other hand, when this new cartridge 1 is connected to a new game device 50, the new game device 50 executes the game program, and a game image such as that shown in FIG. 18 is displayed, for example.

[0141] In this way, the new cartridge 1 can be connected to both the new game device 50 and the old game device 70, and stores programs compatible with each game device. For example, when the new cartridge 1 is connected to the new game device 50, the new game device 50 can execute a first application program, and when the new cartridge 1 is connected to the old game device 70, the old game device 70 can execute a second application program. This ensures compatibility of the new cartridge 1 while allowing programs to be executed that are compatible with each game device, and programs to be executed in accordance with the performance of each game device.

[0142] Furthermore, if the above-mentioned display program is stored in the new cartridge 1, it is possible to inform the user that the game program cannot be executed on the old game device 70. For example, if an unexpected cartridge is inserted into a game device, the OS (operating system) of the game device may display a predetermined warning. However, in this case, it may be difficult for the user to determine the cause, whether it is a compatibility issue or a hardware or software malfunction. In this embodiment, a display program is stored in the new cartridge 1, and the old game device 70 can be made to execute the display program. This makes it possible to provide a display that is easy for the user to understand.

[0143] (Description of Terminals T of New Cartridge 1) Next, we will explain each terminal T of the new cartridge 1. Figure 21 is a diagram showing the details of terminals T1 to T16 provided on the front surface of the new cartridge 1. Figure 22 is a diagram showing the function of each terminal T of the new cartridge 1.

[0144] The new cartridge 1 is inserted bottom-first into the insertion opening of the first slot 51 of the new game device 50 or the second slot 71 of the old game device 70. Here, the direction in which the new cartridge 1 is inserted or removed (the up-and-down direction in FIG. 21; the positive and negative y-axis directions) is referred to as the "first direction," and the direction perpendicular to the first direction (the left-and-right direction in FIG. 21; the positive and negative x-axis directions) is referred to as the second direction.

[0145] As shown in FIG. 21 , a terminal arrangement area is provided on the surface of the substrate 40, and terminals T1 to T16 are arranged in the terminal arrangement area. The terminal arrangement area is divided into an upper area and a lower area. Terminals T1, T4, T7, T10, T15, and T16 are long terminals that extend in a first direction and straddle the upper and lower areas of the terminal arrangement area. Terminals T2, T5, T8, T11, and T13 are short terminals that extend in the first direction and are arranged in the upper area of ​​the terminal arrangement area. Terminals T3, T6, T9, T12, and T14 are short terminals that extend in the first direction and are arranged in the lower area of ​​the terminal arrangement area.

[0146] The positions in the y-axis direction of the upper ends of the long terminals T1, T4, T7, T10, T15, and T16 and the positions in the y-axis direction of the short terminals T2, T5, T8, T11, and T13 arranged in the upper region are the same. The positions in the y-axis direction of the lower ends of the short terminals T2, T5, T8, T11, and T13 arranged in the upper region are the same. The positions in the y-axis direction of the upper ends of the short terminals T3, T6, T9, T12, and T14 arranged in the lower region are the same. The positions in the y-axis direction of the lower ends of the short terminals T3, T6, T9, T12, and T14 arranged in the lower region are the same. The positions in the x-axis direction of the terminals T2 and T3 are the same, the positions in the x-axis direction of the terminals T5 and T6 are the same, the positions in the x-axis direction of the terminals T8 and T9 are the same, the positions in the x-axis direction of the terminals T11 and T12 are the same, and the positions in the x-axis direction of the terminals T13 and T14 are the same.

[0147] The positions in the y-axis direction of the bottom ends of the long terminals T1, T4, T7, T10, T15, and T16 are all different. Specifically, terminal T15 is the longest, and its bottom end is closest to the bottom end of the new cartridge 1. The positions in the y-axis direction of the bottom ends of terminals T7 and T10 are the same. The bottom ends of terminals T7 and T10 are higher than the bottom end of terminal T15 and lower than the bottom end of terminal T3. The position in the y-axis direction of the bottom end of terminal T16 is the same as the position in the y-axis direction of the bottom end of terminal T3. The position in the y-axis direction of the bottom end of terminal T1 is higher than the bottom end of terminal T3, and is the uppermost position.

[0148] The width (length in the x-axis direction) of each of the terminals T1 to T16 is the same. The width of each of the terminals T1 to T16 may be, for example, approximately 1 mm. The lengths in the y-axis direction of the short terminals T2, T5, T8, T11, and T13 arranged in the upper region and the short terminals T3, T6, T9, T12, and T14 arranged in the lower region are all the same, and may be, for example, approximately 4.5 mm. The length in the y-axis direction of terminal T15 may be, for example, approximately 11.3 mm. The lengths in the y-axis direction of terminals T7 and T10 may be, for example, approximately 10.9 mm. The length in the y-axis direction of terminal T1 may be, for example, approximately 10.1 mm.

[0149] The distance in the x direction between multiple terminals exposed from the same opening 23 may be, for example, approximately 0.2 mm. Specifically, the distance between terminals T1 and T2, the distance between terminals T4 and T5, the distance between terminals T7 and T8, the distance between terminals T10 and T11, the distance between terminals T13 and T15, and the distance between terminals T15 and T16 may all be equal and approximately 0.2 mm. The distance in the x direction between two terminals separated by separator 24 may be, for example, approximately 1.0 mm. Specifically, the distance between terminals T2 and T4, the distance between terminals T5 and T7, the distance between terminals T8 and T10, the distance between terminals T11 and T13, and the distance between terminals T12 and T14 may all be equal and approximately 1.0 mm.

[0150] As shown in FIG. 22 , terminal T1 is a ground terminal. Terminal T1 is grounded by being connected to the ground terminal P0 of the new game device 50 or old game device 70. Terminal T1 also functions as a detection terminal that allows the new game device 50 or old game device 70 to detect the new cartridge 1. In the following figures, the ground terminal will be referred to as "GND" and the detection terminal will be referred to as "DET1." Terminal T1 functions as a ground terminal and a detection terminal whether the new cartridge 1 is operating in normal mode or in compatibility mode.

[0151] Furthermore, terminal T2 is a strobe terminal for outputting a strobe signal to the new game device 50 or the old game device 70. In the following figures, terminal T2 may be referred to as "DQS." Terminal T2 functions as a strobe terminal whether the new cartridge 1 is operating in normal mode or in compatible mode. As will be described in detail later, terminal T2 is used as a mode determination terminal for determining whether the new cartridge 1 should be started in normal mode or compatible mode when the new cartridge 1 is inserted into the new game device 50 or the old game device 70.

[0152] Terminal T3 is a clock terminal for inputting a clock signal from the game device. In the following drawings, terminal T3 may be referred to as "CLK." Terminal T3 functions as a clock terminal whether the new cartridge 1 is operating in normal mode or in compatible mode.

[0153] When the new cartridge 1 is connected to the new game device 50 or the old game device 70, a clock signal from the new game device 50 or the old game device 70 is input to terminal T3. Furthermore, when the new cartridge 1 is connected to the new game device 50 or the old game device 70, a strobe signal from the new cartridge 1 is output from terminal T2 to the new game device 50 or the old game device 70.

[0154] The clock signal is a signal used when the game device transmits data to the new cartridge 1 via the data input / output terminal. The clock signal is a high-frequency signal that periodically changes between a high-voltage state and a low-voltage state. The voltage state of the data input / output terminal at the timing of the clock signal switching (in other words, the timing of the switching between low and high voltage) determines what data ("0" or "1") is flowing through the data input / output terminal. In other words, the clock terminal T3 is a terminal through which a high-frequency signal flows, and is a terminal where the voltage changes frequently.

[0155] The strobe signal is a signal output from the new cartridge 1 and is used when the game device reads data from the new cartridge 1 via the data input / output terminal. Like the clock terminal T3, the strobe terminal T2 is a terminal through which a high-frequency signal flows and where the voltage changes frequently.

[0156] When the new cartridge 1 is operating in normal mode, the terminal T4 functions as a terminal that inputs commands from the new game device 50 and outputs responses to the new game device 50. Note that in the diagram, the terminal T4, which inputs commands from the new game device 50 and outputs responses to the new game device 50, is sometimes referred to as "CMD." Commands from the new game device 50 to the new cartridge 1 include, for example, commands for reading data, commands for writing data, and commands for inquiring about the status of the new cartridge 1. The responses from the new cartridge 1 to the new game device 50 are responses to these commands. For example, when the new game device 50 reads data stored in the new cartridge 1, the new cartridge 1 receives a command for reading data via the terminal T4. When this read command is being transmitted, the terminal T4 changes between a high-voltage state and a low-voltage state, but the frequency is lower than that of the clock terminals. Furthermore, when data is being read using the data input / output terminal after the command is transmitted, the terminal T4 is maintained in a low-voltage or high-voltage state, and the voltage is approximately constant. The same applies when the new game device 50 writes data to the new cartridge 1. That is, after the new game device 50 transmits a command to write data to the new cartridge 1, while the data is being read using the data input / output terminal, the voltage at terminal T4 remains approximately constant.

[0157] Furthermore, when the new cartridge 1 is operating in compatibility mode, terminal T4 functions as a terminal for inputting a chip enable signal from the old game device 70. The chip enable terminal T4 is used when data communication (e.g., reading and writing image data, program data, etc., and inputting and outputting commands) is performed between the new cartridge 1 and the old game device 70. For example, while no data communication is performed between the new cartridge 1 and the old game device 70, the chip enable terminal T4 is maintained in a high voltage state. On the other hand, while data communication is performed between the new cartridge 1 and the old game device 70, the chip enable terminal T4 is maintained in a low voltage state.

[0158] 22, terminals T5, T6, T8, T9, T11, T12, T13, and T14 are data input / output terminals for inputting and outputting data between the new cartridge 1 and the game device. The data input / output terminals T5, T6, T8, T9, T11, T12, T13, and T14 may be referred to as IO0, IO1, IO2, IO3, IO4, IO5, IO6, and IO7, respectively. When the new cartridge 1 operates in normal mode, the terminals T5, T6, T8, T9, T11, T12, T13, and T14 function as data input / output terminals for transmitting and receiving signals conforming to the first standard. When the new cartridge 1 operates in compatible mode, the terminals T5, T6, T8, T9, T11, T12, T13, and T14 function as data input / output terminals for transmitting and receiving signals conforming to the second standard.

[0159] Data communication via the data input / output terminal is performed at a relatively high speed, and high-frequency signals flow through the data input / output terminal during data input / output. In other words, the data input / output terminal is a terminal where the voltage changes frequently.

[0160] Terminal T7 is a power supply terminal for supplying power to the control unit 12. Terminal T7 may be referred to as "Vcc." When the new cartridge 1 is electrically connected to the new game device 50, a predetermined voltage is supplied from the new game device 50 to terminal T7, and the control unit 12 of the new cartridge 1 operates on this power supply voltage. When the new cartridge 1 is electrically connected to the old game device 70, the same voltage is supplied from the old game device 70 to terminal T7, and the control unit 12 of the new cartridge 1 operates on this power supply voltage. The power supply voltage supplied to terminal T7 from the new game device 50 or the old game device 70 is, for example, approximately 3.1 V. The power supply voltage supplied to terminal T7 is approximately constant. In other words, the power supply terminal T7 is not a terminal through which high-frequency signals flow, such as a clock terminal, a strobe terminal, or a data input / output terminal, but rather a terminal through which voltage changes occur less frequently.

[0161] Terminal T10 is a power supply terminal for data input / output. Terminal T10 may be referred to as "Vccio." When the new cartridge 1 is electrically connected to the new game device 50, a predetermined power supply voltage for data input / output is supplied from the new game device 50 to terminal T10. When the new cartridge 1 is electrically connected to the old game device 70, the same power supply voltage for data input / output is supplied from the old game device 70 to terminal T10. Power is supplied to the data input / output terminal by this data input / output power supply, and data communication is carried out between the new game device 50 or old game device 70 and the new cartridge 1 via this data input / output terminal. The power supply voltage supplied to terminal T10 from the new game device 50 or old game device 70 is, for example, approximately 1.8 V. This power supply voltage supplied to terminal T10 is approximately constant. In other words, the power supply terminal T10 is not a terminal through which high-frequency signals flow, like a clock terminal, strobe terminal, or data input / output terminal, and can be said to be a terminal where voltage changes less frequently.

[0162] 22, terminal T15 is a ground terminal. Terminal T15 may be written as "GND." By connecting terminal T15 to the ground terminal of the new game device 50 or the old game device 70, the new cartridge 1 is grounded. Because terminal T15 is a ground terminal, the voltage is approximately constant. In other words, terminal T15 is not a terminal through which high-frequency signals flow, such as a clock terminal, strobe terminal, or data input / output terminal, but rather a terminal whose voltage changes infrequently.

[0163] Terminal T16 is a reset terminal for inputting a reset release signal from the new game device 50 or old game device 70. Terminal T16 may be written as "RES." When a reset release signal is input to the new cartridge 1, the new cartridge 1 starts up its firmware and begins operation in normal mode or compatibility mode, and also performs initialization. After the new cartridge 1 and the new game device 50 or old game device 70 are electrically connected, terminal T16 is maintained in a high-voltage state (reset release state). For this reason, the reset terminal T16 is not a terminal through which high-frequency signals flow, such as a clock terminal, strobe terminal, or data input / output terminal, but rather can be said to be a terminal through which voltage changes occur less frequently.

[0164] In the new cartridge 1, among the multiple terminals exposed from the same opening 23, a terminal with a high frequency of voltage changes and a terminal with a low frequency of voltage changes are arranged adjacent to each other. This reduces the influence of noise on adjacent terminals. For example, terminals T12 and T14 are separated by a separator 24 and are relatively far apart, so terminals T12 and T14 are less susceptible to the influence of noise on each other.

[0165] For example, when the new cartridge 1 is connected to the new game device 50, terminal T4 functions as a command input / response output terminal, and when the new cartridge 1 is connected to the old game device 70, terminal T4 functions as a chip enable input terminal. Terminal T4 is also adjacent to data input / output terminals T5 and T6. Whether the new cartridge 1 is connected to the new game device 50 or the old game device 70, terminal T4 maintains a substantially constant voltage when data is being input or output using the data input / output terminals T5 and T6. Furthermore, when the new cartridge 1 is connected to the new game device 50, even when commands are being sent or received from terminal T4, the frequency of voltage changes is relatively low. Therefore, data input / output terminals T5 and T6 are less susceptible to noise from the adjacent terminal T4. Terminal T4 is also located next to the strobe terminal T2 and the clock terminal T3. Whether the new cartridge 1 is connected to the new game device 50 or the old game device 70, the frequency of changes in the voltage at terminal T4 is low, and there is a relatively large distance between terminal T4 and the strobe terminal T2 and clock terminal T3. For this reason, the strobe terminal T2 and clock terminal T3 are less susceptible to noise from terminal T4.

[0166] Here, we will explain the old cartridge 7. Figure 23 is a front view of the old cartridge 7. Figure 24 is a diagram showing the functions of each terminal T of the old cartridge 7.

[0167] Except for the shape of the notch, the shape and size of the old cartridge 7 are substantially the same as those of the new cartridge 1. Like the new cartridge 1, the old cartridge 7 is inserted into the slot of the new game device 50 or the old game device 70, bottom end first.

[0168] 23 , the old cartridge 7 includes a housing 60. A notch 61 is provided at the right end of the housing 60, extending in the insertion / removal direction (first direction) of the old cartridge 7. Similar to the right-side notch 21 of the new cartridge 1, this notch 61 of the old cartridge 7 functions as a rail when the old cartridge 7 is inserted into the slot of the new game device 50 or old game device 70.

[0169] The old cartridge 7 does not have a notch similar to the right notch 22 provided at the right end and bottom end of the new cartridge 1.

[0170] The housing 60 also has cutouts 62 and 63 on the left end. The cutout 62 on the old cartridge 7 has the same shape as the left-side cutout 25 on the new cartridge 1 and is located in the same position. The cutout 63 on the old cartridge 7 has the same shape as the left-side cutout 26 on the new cartridge 1 and is located in the same position.

[0171] A substrate is housed inside the housing 60. Terminals T1 to T16 are provided on the surface of the substrate.

[0172] Specifically, the terminals T1 to T16 of the old cartridge 7 have the same shape and size as the terminals T1 to T16 of the new cartridge 1. In addition, the terminals T1 to T16 of the old cartridge 7 are located in the same positions as the terminals T1 to T16 of the new cartridge 1.

[0173] 24, the terminal T1 of the old cartridge 7 has the same function as the terminal T1 of the new cartridge 1. The terminals T2 and T3 of the old cartridge 7 have the same function as the terminals T2 and T3 of the new cartridge 1.

[0174] Furthermore, the terminal T4 of the old cartridge 7 has the same function as the terminal T4 when the new cartridge 1 operates in the compatible mode. That is, the terminal T4 of the old cartridge 7 is a chip enable terminal for inputting a chip enable signal.

[0175] Terminals T5 and T6 of the old cartridge 7 are data input / output terminals that transmit and receive signals conforming to the second standard, and have the same functions as terminals T5 and T6 when the new cartridge 1 operates in the compatible mode. Similarly, terminals T8, T9, T11, T12, T13, and T14 of the old cartridge 7 are data input / output terminals that transmit and receive signals conforming to the second standard, just as when the new cartridge 1 operates in the compatible mode.

[0176] Furthermore, terminal T7 of old cartridge 7 is a power supply terminal, has the same function as terminal T7 of new cartridge 1, and is supplied with the same power supply voltage from the game device. Similarly, terminal T10 of old cartridge 7 is a power supply terminal, has the same function as terminal T10 of new cartridge 1, and is supplied with the same power supply voltage from the game device.

[0177] Furthermore, terminal T15 of the old cartridge 7 is a ground terminal and has the same function as terminal T15 of the new cartridge 1. Similarly, terminal T16 of the old cartridge 7 is a reset terminal and has the same function as terminal T16 of the new cartridge 1.

[0178] (Explanation of the first slot 51 of the new game device 50) Next, the first slot 51 of the new game device 50 will be described. Figure 25 is a front view of the cartridge insertion opening of the first slot 51. Figure 26 is a partial enlarged view of the cartridge insertion opening seen from an angle. The direction into the paper of Figure 25 is the cartridge insertion direction (negative y-axis direction). Note that Figures 25 and 26 only show the shape of the cartridge insertion opening of the slot 51, and omit terminals and the like inside the slot.

[0179] The cartridge insertion opening of the first slot 51 has substantially the same shape as the top surface of the new cartridge 1 and is slightly larger than the new cartridge 1. As shown in FIG. 25 , the cartridge insertion opening of the first slot 51 is substantially rectangular. As shown in FIG. 26 , a wall portion 515 is provided on the inner wall of the first slot 51. The wall portion 515 is provided at a position slightly toward the negative y-axis direction from the right end (end in the x-axis direction) and upper end (end in the y-axis direction) of the first slot 51. The wall portion 515 is an example of a guide portion for correctly inserting the cartridge into the first slot 51. As shown in FIG. 26 , the wall portion 515 is provided near the insertion opening and not toward the depth of the first slot 51. Note that the wall portion 515 may be formed to extend from the cartridge insertion opening into the interior of the first slot 51 in the cartridge insertion direction.

[0180] The wall portion 515 is formed in the negative x-axis direction from the end of the first slot 51 in the x-axis direction and in the negative z-axis direction from the end of the first slot 51 in the z-axis direction. The right-side notch 22 and the wall portion 515 function as guides for inserting the cartridge into the first slot 51 in the correct orientation. Furthermore, the right-side notch 21 and the wall portion 515 come into contact with each other during cartridge insertion. The right-side notch 21 also functions as a rail when sliding the cartridge in the insertion direction. The right-side notch 22 may also function as a rail by coming into contact with the wall portion 515 during insertion into the slot, or may be formed so as not to come into contact with the wall portion 515 during insertion into the slot (i.e., not to function as a rail). The user can insert the new cartridge 1 in the insertion direction by inserting the new cartridge 1 into the cartridge insertion opening so that the wall portion 515 and the right-side notch 22 in the first slot 51 align with each other and then pushing the new cartridge 1 in. The right-side notches 22 and 21 provided at one end of the new cartridge 1 and the wall portion 515 provided at a corresponding position in the first slot 51 allow the user to insert the new cartridge 1 in the correct orientation into the cartridge insertion port and easily insert the new cartridge 1 all the way into the first slot 51.

[0181] Figure 27 is a diagram showing the arrangement of multiple terminals P provided inside the first slot 51. Figure 28 is a diagram showing the function of each terminal P provided inside the first slot 51. Figure 27 shows the first slot 51 as viewed from the front when a new cartridge 1 is inserted into the first slot 51. In Figure 27, the new cartridge 1 is indicated by dashed lines, and the components that make up the first slot 51 are indicated by solid lines.

[0182] When the new cartridge 1 is inserted all the way into the first slot 51, the new cartridge 1 is fixed at a predetermined position in the depth direction of the first slot 51 by the locking mechanism.

[0183] As shown in FIG. 27 , a plurality of terminals P0 to P16 are provided inside the first slot 51. The plurality of terminals P are connected to an electronic circuit provided inside the new game device 50. The terminals P0, P2, P4, P5, P7, P8, P10, P11, P13, P15, and P16 are arranged side by side in the horizontal direction (x-axis direction). The terminals P1, P3, P6, P9, P12, and P14 are also arranged side by side in the horizontal direction (x-axis direction). The terminals P1, P3, P6, P9, P12, and P14 are arranged further back in the first slot 51 than the terminals P0, P2, P4, P5, P7, P8, P10, P11, P13, P15, and P16.

[0184] When the new cartridge 1 is fixed in the first slot 51, the terminals P0 and P1 of the first slot 51 are electrically connected to the terminal T1 of the new cartridge 1. Also, when the new cartridge 1 is fixed in the first slot 51, the terminals P2 to P16 of the first slot 51 are electrically connected to the terminals T2 to T16 of the new cartridge 1, respectively.

[0185] As shown in FIG. 28 , terminal P0 of the first slot 51 functions as a ground terminal and is connected to the ground of the electronic circuit provided in the new game device 50. Terminal P1 of the first slot 51 also functions as a detection terminal for detecting a cartridge. Detection terminal P1 is connected to a predetermined terminal of the same electronic circuit or a different electronic circuit provided in the new game device 50. When no cartridge is connected, detection terminal P1 is maintained at a predetermined voltage, and when a cartridge is connected, detection terminal P1 is connected to terminal T1 of the cartridge and is electrically connected to ground terminal P0. When terminal P1 of the first slot 51 is connected to terminal T1 of the new cartridge 1 or old cartridge 7, the new game device 50 detects that the new cartridge 1 or old cartridge 7 has been connected because detection terminal P1 reaches ground potential.

[0186] Terminals P2 to P16 of the first slot 51 have the same functions as terminals T2 to T16 of the new cartridge 1 shown in FIG. 22. Specifically, terminal P2 functions as a strobe terminal for inputting a strobe signal. Terminal P3 functions as a clock terminal for outputting a clock signal. Terminal P4 functions as a terminal for outputting commands to the new cartridge 1 and for inputting responses from the new cartridge 1 when the new game device 50 is operating in normal mode. Terminal P4 also functions as a terminal for outputting a chip enable signal when the new game device 50 is operating in compatibility mode. Terminals P5, P6, P8, P9, and P11 to P14 also function as data input / output terminals for sending and receiving signals conforming to the first standard when the new game device 50 is operating in normal mode, and as data input / output terminals for sending and receiving signals conforming to the second standard when the new game device 50 is operating in compatibility mode. Terminals P7 and P10 function as power supply terminals for supplying power to the cartridge. Terminal P15 also functions as a ground terminal. Furthermore, the terminal P16 functions as a reset terminal that outputs a reset release signal to the cartridge.

[0187] 27, a terminal P17 is provided inside the first slot 51. The terminal P17 is an identification terminal that allows the new game device 50 to identify whether a new cartridge 1 or an old cartridge 7 has been connected.

[0188] Specifically, terminal P17 is provided at one left-right end (x-axis direction end) inside first slot 51. Terminal P17 has a portion P17a extending in the negative y-axis direction (the cartridge insertion direction) and a portion P17b protruding from the negative y-axis end of portion P17a in the negative y-axis direction and in the negative x-axis direction (toward the other end). Portions P17a and P17b form an obtuse angle α. Terminal P17 also has a portion P17c extending from the negative y-axis end of portion P17b in the negative y-axis direction and in the x-axis direction (toward the one end). Portions P17b and P17c form an obtuse angle. Terminal 512 is provided at a position facing portions P17b and P17c of terminal P17 in the X-axis direction.

[0189] Terminal P17 is located at a position that does not contact the housing of the new cartridge 1 accommodated in the first slot 51, and contacts a portion of the housing of the old cartridge 7 when the old cartridge 7 is accommodated. Note that a portion P17a of terminal P17 may contact either the housing of the new cartridge 1 or the housing of the old cartridge 7. Here, "a cartridge being accommodated" in a slot refers to a state in which the cartridge is inserted into the slot and fixed in a predetermined position. When the cartridge is accommodated in a slot, a portion of the cartridge may or may not be exposed from the slot. Specifically, terminals P17 (specifically, P17b and P17c) are accommodated in the space formed by the right-side notch 22 of the new cartridge 1 when the new cartridge 1 is accommodated in the first slot 51. When the new cartridge 1 is inserted into the first slot 51, terminal P17 does not contact terminal 512.

[0190] Terminal P17 is a switch that changes between an ON state and an OFF state. Terminal P17 does not normally come into contact with the opposing terminal 512 and is in an OFF state. When terminal P17 comes into contact with the opposing terminal 512 due to elastic deformation, it changes to an ON state. When the new cartridge 1 is fixed in the first slot 51, terminal P17 maintains its OFF state. On the other hand, when the old cartridge 7 is fixed in the first slot 51, terminal P17 changes to an ON state. A circuit (not shown) that determines whether terminal P17 is in an ON state or an OFF state is provided inside the new game device 50.

[0191] Although not shown in the figures, the second slot 71 of the old game device 70 has the same shape and size as the first slot 51, and the shape of the cartridge insertion opening is also the same. Furthermore, terminals P0 to P16 are provided inside the second slot 71, just like the first slot 51. The positions of the terminals P0 to P16 inside the second slot 71 are the same as the positions of the terminals P0 to P16 inside the first slot 51. On the other hand, the identification terminal P17 is not provided inside the second slot 71.

[0192] (Changes in the State of Each Terminal When the New Cartridge 1 is Inserted) Next, changes in the state of each terminal when the new cartridge 1 is inserted into the first slot 51 will be described.

[0193] 29 to 34 are diagrams for explaining which terminals T and P come into contact with each other as the new cartridge 1 is inserted into the first slot 51. FIG.

[0194] 29, when the new cartridge 1 is inserted into the first slot 51, the ground terminal P15 of the first slot 51 first comes into contact with the ground terminal T15 of the new cartridge 1. When the new cartridge 1 is further pushed deeper into the first slot 51, the power terminal P7 of the first slot 51 then comes into contact with the power terminal T7 of the new cartridge 1 (FIG. 30). The power terminal P10 of the first slot 51 also comes into contact with the power terminal T10 of the new cartridge 1.

[0195] When the new cartridge 1 is further pushed inward into the first slot 51, the reset terminal P16 of the first slot 51 comes into contact with the reset terminal T16 of the new cartridge 1 (FIG. 31). Also, terminals P2 and T3 come into contact, terminals P4 and T4 come into contact, terminals P5 and T6 come into contact, terminals P8 and T9 come into contact, terminals P11 and T12 come into contact, and terminals P13 and T14 come into contact (FIG. 31). When the new cartridge 1 is further pushed in, the ground terminal P0 comes into contact with the ground terminal T1 (FIG. 32).

[0196] When the new cartridge 1 is further pushed in, the terminals P2, P3, P5, P6, P8, P9, P11, P12, P13, and P14 come into contact with the terminals T2, T3, T5, T6, T8, T9, T11, T12, T13, and T14, respectively (FIG. 33).

[0197] As the new cartridge 1 is further pushed in, the detection terminal P1 of the first slot 51 finally comes into contact with the detection terminal T1 of the new cartridge 1. This contact between the detection terminal P1 and the detection terminal T1 causes the new game device 50 to detect the connection of the new cartridge 1.

[0198] As described above, the first slot 51 is provided with a terminal P17, which is normally in an OFF state and not connected to the terminal 512. When the new cartridge 1 is inserted into the first slot 51, the terminal P17 does not come into contact with the new cartridge 1, and therefore is not connected to the terminal 512 and remains in an OFF state.

[0199] (Changes in the State of Each Terminal When the Old Cartridge 7 is Inserted) Next, changes in the state of each terminal when the old cartridge 7 is inserted into the first slot 51 will be described.

[0200] Figure 35 is a diagram showing the state when terminal P17 of the first slot 51 changes from the OFF state to the ON state. Figure 36 is a diagram showing the state after Figure 35 when detection terminal T1 of the old cartridge 7 comes into contact with detection terminal P1 of the first slot 51. Figure 37 is a diagram showing the state after Figure 36 when the old cartridge 7 is fixed in the first slot 51.

[0201] The positions, sizes, and shapes of the terminals T1 to T16 of the old cartridge 7 are the same as the positions, sizes, and shapes of the terminals T1 to T16 of the new cartridge 1. Therefore, when the old cartridge 7 is inserted into the first slot 51, the terminals P other than the detection terminal P1 come into contact with the terminals T of the old cartridge 7 in the same order as described in Figures 29 to 33.

[0202] 35, when the old cartridge 7 is inserted into the first slot 51, the housing of the old cartridge 7 comes into contact with the terminal P17, causing the terminal P17 to elastically deform and connect to the terminal 512. This changes the identification terminal P17 to the ON state. At this point, the detection terminal P1 is not in contact with the detection terminal T1.

[0203] When the old cartridge 7 is pushed further in, the detection terminal P1 comes into contact with the detection terminal T1 (FIG. 36). This contact between the detection terminal P1 and the detection terminal T1 causes the new game device 50 to detect the connection of the old cartridge 7. The old cartridge 7 is then fixed in the first slot 51 (FIG. 37).

[0204] 29 to 34, when the new cartridge 1 is inserted into the first slot 51, the detection terminal P1 comes into contact with the detection terminal T1 without the terminal P17 coming into contact with the terminal 512. On the other hand, as described with reference to FIGS. 35 to 37, when the old cartridge 7 is inserted into the first slot 51, the terminal P17 comes into contact with the housing of the old cartridge 7, thereby connecting the terminal P17 to the terminal 512 and changing the state of the terminal P17 to the ON state. After the state of the terminal P17 changes to the ON state, the detection terminal P1 comes into contact with the detection terminal T1.

[0205] When detection terminal P1 comes into contact with detection terminal T1, the new game device 50 determines whether a new cartridge 1 or an old cartridge 7 has been connected based on the state of terminal P17 at that time. Specifically, if terminal P17 is in the OFF state when detection terminal P1 comes into contact with detection terminal T1, the new game device 50 detects that a new cartridge 1 has been connected. On the other hand, if terminal P17 is in the ON state when detection terminal P1 comes into contact with detection terminal T1, the new game device 50 detects that an old cartridge 7 has been connected.

[0206] In this way, when an old cartridge 7 is inserted into the new game device 50, the identification terminal P17 comes into contact with the housing of the old cartridge 7, changing the identification terminal P17 to the ON state, and thereafter the detection terminal T1 and the detection terminal P1 come into contact. Also, when a new cartridge 1 is inserted into the new game device 50, the identification terminal P17 is maintained in the OFF state, and the detection terminal T1 and the detection terminal P1 come into contact. That is, when the new game device 50 detects a cartridge, the identification terminal P17 is configured to be either in the ON state or the OFF state. If the state of the identification terminal P17 were configured to change after the new game device 50 detected a cartridge, the new game device 50 would not be able to determine what type of cartridge has been connected after detecting the connection of the cartridge until the state of the identification terminal P17 was determined. Furthermore, if cartridge identification is to be performed after a predetermined time has elapsed since the cartridge was detected, it is difficult to appropriately set the predetermined time because the speed at which the user inserts the cartridge is unknown. The new game device 50 can identify whether the detected cartridge is a new cartridge 1 or an old cartridge 7 at the time of detecting the cartridge (the time when the detection terminal P1 comes into contact with the detection terminal T1), and can perform processing according to the type of cartridge identified.

[0207] Furthermore, whether an old cartridge 7 or a new cartridge 1 is inserted into the first slot 51 of the new game device 50, the ground terminal T15 first comes into contact with the ground terminal P15 of the first slot 51. This makes the cartridge electrically stable, allowing it to be safely connected to the new game device 50.

[0208] Note that the ground terminal T15 and the ground terminal P15 do not necessarily have to come into contact first. For example, the ground terminal T15 and the ground terminal P15 may come into contact after the state of the identification terminal P17 is determined, and then the detection terminal T1 and the detection terminal P1 may come into contact. Also, for example, the detection terminal T1 and the detection terminal P1 may come into contact after the state of the identification terminal P17 is determined, and then the ground terminal T15 and the ground terminal P15 may come into contact.

[0209] The identification terminal P17 also has a portion P17a extending in the negative y-axis direction, a portion P17b extending from the bottom end of portion P17a in the negative y-axis direction and the negative x-axis direction, and a portion P17c extending from the bottom end of portion P17b in the negative y-axis direction and the x-axis direction. Portions P17a and P17b form an obtuse angle, and portions P17b and P17c form an obtuse angle. This prevents the tip of the identification terminal P17 (the tip of portion P17c) from contacting the housing of the old cartridge 7 and becoming less likely to get caught on the housing when the old cartridge 7 is inserted into or removed from the first slot 51 of the new game device 50. This prevents the identification terminal P17 from deforming more than expected and becoming plastically deformed during insertion or removal.

[0210] The above-described identification terminal P17 and terminal 512 are merely examples, and the structure of the identification terminal for identifying the type of connected cartridge is not limited to the above.

[0211] (Processing sequence when a new cartridge is connected to a new game device) Next, a description will be given of the processing in the new game device 50 and the new cartridge 1 when the new cartridge 1 is connected to the new game device 50. Figure 38 is an example of a sequence diagram of the new game device 50 and the new cartridge 1 when the new cartridge 1 is connected to the new game device 50.

[0212] FIG. 38 shows the change in voltage level of each terminal P of the new game device 50 over time, and the processing in the new game device 50 and new cartridge 1. As shown in FIG. 38, when no cartridge is connected to the new game device 50, the voltage level of the detection terminal P1 (DET1) of the new game device 50 is maintained at "high" (denoted as "H" in the figure). Furthermore, when the identification terminal P17 is not in contact with the terminal 512, the voltage level of the identification terminal P17 (DET2) is maintained at "high." When the detection terminal P1 of the new game device 50 is connected to the detection terminal T1 of the new cartridge 1, the voltage level of the detection terminal P1 changes from "high" to "low" (denoted as "L" in the figure). The SoC 55 of the new game device 50 detects this change in the voltage level of the detection terminal P1. The new game device 50 checks the voltage level of the identification terminal P17 at this time and determines whether the new cartridge 1 or the old cartridge 7 has been connected. In FIG. 38, the voltage level of the identification terminal P17 is "high", so the identification terminal P17 is not in contact with the terminal 512, and the new game device 50 determines that the connected cartridge is new cartridge 1.

[0213] When the new game device 50 detects that a cartridge has been connected, it performs a switching process. In this switching process, when the old cartridge 7 is connected to the new game device 50, a switching signal is sent from the SoC 55 to the switching units 52 and 53. When this switching signal is received, the switching units 52 and 53 switch from the bypass path to the first path. On the other hand, when the new game device 50 detects that the new cartridge 1 has been connected, it terminates the switching process without sending the switching signal. As a result, when the new cartridge 1 is connected, the new game device 50 enters normal mode and communicates with the new cartridge 1 via the bypass path (based on the first standard). Note that by default, the first path is active, and when the old cartridge 7 is connected to the new game device 50, the path is not switched, and when the new cartridge 1 is connected to the new game device 50, the path may be switched from the first path to the bypass path. Furthermore, after the new game device 50 detects the cartridge, a dead period may be provided to prevent chattering before the switching process is performed.

[0214] Next, the new game device 50 supplies power to the new cartridge 1. Specifically, the new game device 50 changes the voltage level of the power supply terminal P7 from "low" to "high." This causes power to be supplied to the control unit 12 of the new cartridge 1, and the new cartridge 1 begins operation. The new game device 50 then changes the voltage level of the power supply terminal P10 from "low" to "high." The new game device 50 also changes the voltage level of the terminal P4 (CMD) from "low" to "high." Furthermore, when the new cartridge 1 is connected, the new game device 50 maintains the voltage level of the terminal P2 (DQS) at "low."

[0215] Next, the new game device 50 transmits a reset release signal to the new cartridge 1. Specifically, the new game device 50 changes the voltage level of the reset terminal P16 from "low" to "high."

[0216] Meanwhile, after being inserted into the first slot 51 of the new game console 50, the new cartridge 1 maintains a reset release wait state until it receives a reset release signal from the new game console 50. The new cartridge 1 (the CPU 120 of the new cartridge 1) receives the reset release signal from the new game console 50 by detecting that the voltage level at terminal T16 has changed from "low" to "high." Upon receiving the reset release signal from the new game console 50, the new cartridge 1 checks the voltage level at terminal T2 (DQS). If the voltage level at terminal T2 is "low," the new cartridge 1 determines that the new cartridge 1 is connected to the new game console 50 and starts up the new cartridge 1 in normal mode. Specifically, the CPU 120 of the new cartridge 1 starts up the normal firmware. The new cartridge 1 then performs initialization to make it usable by the new game console 50. The new game console 50 waits until the initialization of the new cartridge 1 is complete. Once the initialization of the new cartridge 1 is complete, the new cartridge 1 becomes capable of communicating data with the new game console 50. When the new cartridge 1 and the new game device 50 are operating in normal mode, data communication between the new cartridge 1 and the new game device 50 is performed in accordance with the first standard.

[0217] (Processing sequence when a new cartridge is connected to an old game device) Next, a description will be given of the processing in the old game device 70 and the new cartridge 1 when the new cartridge 1 is connected to the old game device 70. Figure 39 is an example of a sequence diagram of the old game device 70 and the new cartridge 1 when the new cartridge 1 is connected to the old game device 70.

[0218] The second slot 71 of the old game device 70 does not have the identification terminal P17 that is provided on the first slot 51 of the new game device 50. As shown in FIG. 39 , the old game device 70 detects that a cartridge has been connected, and after a predetermined time has elapsed, changes the voltage level of the power supply terminal P7 from "low" to "high" at the same timing as the new game device 50. Thereafter, the old game device 70 changes the voltage level of the power supply terminal P10 from "low" to "high." The old game device 70 also changes the voltage level of the terminal P2 (DQS) from "low" to "high." The old game device 70 also changes the voltage level of the terminal P4 (CEB) from "low" to "high." Next, the old game device 70 sends a reset release signal to the new cartridge 1 by changing the voltage level of the reset terminal P16 from "low" to "high." The old game device 70 also performs the same process when an old cartridge 7 is connected.

[0219] When the new cartridge 1 receives the reset release signal, it checks the voltage level of terminal T2 (DQS). If the voltage level of terminal T2 is "high," it determines that the new cartridge 1 is connected to the old game device 70 and starts up the new cartridge 1 in compatibility mode. Specifically, the CPU 120 of the new cartridge 1 starts up the compatible firmware. The new cartridge 1 then performs initialization. The old game device 70 waits until the initialization of the new cartridge 1 is complete. Once the initialization of the new cartridge 1 is complete, the new cartridge 1 becomes able to communicate data with the old game device 70. When the new cartridge 1 is operating in compatibility mode, data communication between the new cartridge 1 and the old game device 70 is performed based on the second standard.

[0220] It should be noted that the new cartridge 1 may determine whether it is connected to the new game device 50 or the old game device 70 by a method other than the voltage level of terminal T2. For example, when the new game device 50 detects that the new cartridge 1 has been connected, it may send a signal indicating that it is the new game device 50 to the new cartridge 1 via a terminal other than terminal T2. If the new cartridge 1 receives this signal, it may determine that it is connected to the new game device 50 and start up in normal mode, and if it does not receive this signal, it may determine that it is connected to the old game device 70 and start up in compatibility mode.

[0221] (New Cartridge Processing Flow) Figure 40 is a flowchart showing an example of the processing that is carried out when the new cartridge 1 receives a reset release signal from the game device. The processing shown in Figure 40 is carried out by the control unit 12 (e.g., CPU 120) of the new cartridge 1 executing a boot program that has been stored in advance in the new cartridge 1.

[0222] 40, when the new cartridge 1 (CPU 120 thereof) receives a reset release signal, it determines whether the new cartridge 1 is connected to the old game device 70 (step S101). This determination determines whether the new cartridge 1 should be started in normal mode or compatibility mode, and whether communication between the new cartridge 1 and the game device should be based on the first standard or the second standard. Specifically, the new cartridge 1 checks the voltage level at terminal T2, and if the voltage level at terminal T2 is "high," it determines that it is connected to the old game device 70.

[0223] If the determination in step S101 is NO, i.e., if the new cartridge 1 is connected to the new game device 50, the new cartridge 1 starts up the standard firmware (step S102). After starting up the standard firmware, the new cartridge 1 performs initialization (step S103). Once initialization is complete, the new cartridge 1 begins operating in standard mode (step S104). From then on, the various hardware components of the new cartridge 1, including the first standard circuit 121 and storage medium control unit 123, are controlled based on the standard firmware until the power supply from the game device is stopped.

[0224] In normal mode, the new cartridge 1 and the new game console 50 communicate based on the first standard. For example, when the new game console 50 reads data from (the storage medium 11 of) the new cartridge 1, the new game console 50 sends a read command to read the data from terminal P4. The new cartridge 1 outputs a response to the command from terminal T4. Next, the new cartridge 1 reads data from the storage medium 11 in response to the read command from the new game console 50, and sends the read data from at least one of the multiple data input / output terminals T (T5, T6, T8, T9, T11, T12, T13, T14). Specifically, in response to the read command from the new game console 50, the CPU 120 of the new cartridge 1 sends an instruction to the storage medium control unit 123 to read data from the storage medium 11. The storage medium control unit 123 reads the data from the storage medium 11. The CPU 120 also sends an instruction to the first standard circuit 121 to send out the data read from the storage medium 11. This causes the first standard circuit 121 to send out a signal conforming to the first standard, corresponding to the data read from the storage medium 11, from at least one of the multiple data input / output terminals T. In this way, the new game device 50 reads the desired data from the new cartridge 1.

[0225] Furthermore, when the new game device 50 writes data to the new cartridge 1, the new game device 50 sends a write command for writing data from terminal P4. The new cartridge 1 outputs a response corresponding to the command from terminal T4. Next, the new game device 50 sends data corresponding to the write command from at least one of the multiple data input / output terminals P (P5, P6, P8, P9, P11, P12, P13, P14). In response to the write command from the new game device 50, the CPU 120 of the new cartridge 1 sends an instruction to the first-standard circuit 121 to receive data. The first-standard circuit 121 processes the signal conforming to the first standard received via at least one of the multiple data input / output terminals T, and transmits data corresponding to the processing results to the storage medium control unit 123. The CPU 120 sends an instruction to the storage medium control unit 123 to write the data to the storage medium 11. In this way, the data from the new game device 50 is written to the storage medium 11 of the new cartridge 1 .

[0226] The new game device 50 may also send a command from terminal P4 to acquire the status of the new cartridge 1. In response to receiving the command, the new cartridge 1 sends a response according to the status of the new cartridge 1 from terminal T4.

[0227] The new cartridge 1 enters a power-saving state while no data is being sent or received between it and the new game device 50. Even when the new cartridge 1 is in the power-saving state, it can receive commands from the new game device 50 via terminal T4. If the new cartridge 1 receives a command from the new game device 50 via terminal T4 while in the power-saving state, it will return a response according to the command and return to the normal state from the power-saving state.

[0228] On the other hand, if the determination in step S101 is YES, the new cartridge 1 starts the compatible firmware (step S105). After starting the compatible firmware, the new cartridge 1 performs initialization (step S106). Once initialization is complete, the new cartridge 1 operates in compatible mode (step S107). From then on, various hardware components, including the second-standard circuit 122 and storage medium control unit 123 of the new cartridge 1, are controlled based on the compatible firmware until the power supply from the game device is stopped.

[0229] In the compatibility mode, the new cartridge 1 and the old game console 70 communicate based on the second standard. For example, when the old game console 70 reads data from the new cartridge 1 (storage medium 11), the old game console 70 transmits a chip enable signal by changing the voltage level of terminal P4 from "high" to "low" in order to read the data from the new cartridge 1. The old game console 70 then transmits a read command to read the data from at least one of the multiple data input / output terminals P. In response to the input of the chip enable signal (in response to a change in the voltage level of terminal T4), the new cartridge 1 returns from the power-saving state to the normal state. In other words, the new cartridge 1 returns from the power-saving state to the normal state based on the activated compatibility firmware. This enables the new cartridge 1 to receive commands from the old game console 70 via the data input / output terminal T. The new cartridge 1 receives a read command via at least one of the multiple data input / output terminals T, reads data from the storage medium 11 in response to the read command, and transmits the read data from at least one of the multiple data input / output terminals T. Specifically, the CPU 120 of the new cartridge 1 transmits an instruction to the storage medium control unit 123 to read data from the storage medium 11 in response to the read command from the old game device 70. The storage medium control unit 123 reads the data from the storage medium 11. The CPU 120 also transmits an instruction to the second-standard circuit 122 to transmit the data read from the storage medium 11. In response to this, the second-standard circuit 122 transmits a signal conforming to the second standard, corresponding to the data read from the storage medium 11, from at least one of the multiple data input / output terminals T. In this way, the old game device 70 reads the desired data from the new cartridge 1.

[0230] Writing data from the old game device 70 to the new cartridge 1 is prohibited. For example, even if the new cartridge 1 receives a write command from the old game device 70, it does not write data to the storage medium 11, but instead sends a message to the old game device 70 that writing is prohibited. This improves security. Writing data from the old game device 70 to the new cartridge 1 may be permitted. When writing data from the old game device 70 to the new cartridge 1 is permitted and the old game device 70 writes data to the new cartridge 1, the old game device 70 writes data as follows: First, the old game device 70 sends a chip enable signal by changing the voltage level of terminal P4 from "high" to "low." Then, the old game device 70 sends a write command to write data from at least one of the multiple data input / output terminals P. The new cartridge 1 receives the write command via at least one of the multiple data input / output terminals T and writes the data to the storage medium 11. Specifically, in response to a write command from the new game device 50, the CPU 120 of the new cartridge 1 sends an instruction to the second-standard circuit 122 to receive data. The second-standard circuit 122 processes signals conforming to the second standard from at least one of the multiple data input / output terminals T, and transmits data corresponding to the processing results to the storage medium control unit 123. The CPU 120 sends an instruction to the storage medium control unit 123 to write the data to the storage medium 11. In this way, the data from the old game device 70 is written to the storage medium 11 of the new cartridge 1.

[0231] As described above, the new cartridge 1 has normal firmware for operating the new cartridge 1 in normal mode and compatible firmware for operating the new cartridge 1 in compatible mode. When the new cartridge 1 is connected to the new game device 50, the normal firmware is activated, and communication between the new cartridge 1 and the new game device 50 is based on a first standard. When the new cartridge 1 is connected to the old game device 70, the compatible firmware is activated, and communication between the new cartridge 1 and the old game device 70 is based on a second standard. Different firmware is activated depending on whether the new cartridge 1 is connected to the new game device 50 or the old game device 70, allowing communication to be performed using a standard appropriate for the connected game device. Furthermore, because the normal firmware and the compatible firmware are separate, for example, even if a malfunction occurs in one firmware, it does not affect the other firmware. For example, even if a malfunction occurs in the compatible firmware, the normal firmware can operate normally, and the new cartridge 1 can be connected to the new game device 50 and the game program stored in the new cartridge 1 can be executed.

[0232] (Processing sequence when old cartridge is connected to new game device) Next, a description will be given of the processing in the new game device 50 and the old cartridge 7 when the old cartridge 7 is connected to the new game device 50. Figure 41 is an example of a sequence diagram of the new game device 50 and the old cartridge 7 when the old cartridge 7 is connected to the new game device 50.

[0233] 41, when the new game device 50 detects that an old cartridge 7 has been connected, it performs a switching process. In this switching process, a switching signal is sent from the SoC 55 to the switching units 52 and 53, and the switching units 52 and 53 switch from the bypass path to the first path. As a result, the new game device 50 operates in compatibility mode and communicates with the old cartridge 7 using the first path based on the second standard.

[0234] After the switching process, as in FIG. 38 , the new game device 50 supplies power and changes the voltage level at terminal P4 from "low" to "high." Furthermore, if an old cartridge 7 is connected, the new game device 50 changes the voltage level at terminal P2 from "low" to "high." The new game device 50 then transmits a reset release signal to the old cartridge 7. Note that the timing for changing the voltage level at terminal P2 from "low" to "high" may be any timing between the time the new game device 50 detects the connection of the old cartridge 7 and the time it transmits the reset release signal to the old cartridge 7.

[0235] When the old cartridge 7 receives a reset release signal from the new game device 50, it starts up the firmware and performs initialization. Once the initialization of the old cartridge 7 is complete, the old cartridge 7 becomes able to perform data communication with the new game device 50. Data communication between the old cartridge 7 and the new game device 50 is performed based on the second standard.

[0236] As described above, the new cartridge 1 of this embodiment can be connected to both the new game device 50 and the old game device 70. When the new cartridge 1 is connected to the new game device 50, the new cartridge 1 is started up in normal mode (normal firmware is started up), and communication between the new cartridge 1 and the new game device 50 is based on the first standard. When the new cartridge 1 is connected to the old game device 70, the new cartridge 1 is started up in compatible mode (compatible firmware is started up), and communication between the new cartridge 1 and the old game device 70 is based on the second standard.

[0237] This makes it possible to provide a new cartridge 1 that is compatible with both the new game device 50 and the old game device 70. When connected to the new game device 50, the new cartridge 1 communicates with the new game device 50 based on the first standard, and when connected to the old game device 70, the new cartridge 1 can communicate with the old game device 70 based on the second standard, allowing communication to be performed in accordance with the capabilities of each game device.

[0238] Furthermore, the new cartridge 1 can be configured as a shared cartridge. Specifically, a first application program, first image data, and first metadata are stored in a first storage area of ​​the storage medium 11 as data for the new game device 50 (see FIG. 15). Furthermore, a second application program, second image data, and second metadata are stored in a second storage area of ​​the storage medium 11 as data for the old game device 70. When the new cartridge 1 is connected to the new game device 50, the first application program is read by the new game device 50. When the new cartridge 1 is connected to the old game device 70, the second application program is read by the old game device 70. This makes it possible to execute application programs that make the most of the capabilities of each game device.

[0239] In another aspect, when the new cartridge 1 is configured as a shared cartridge, the first storage area stores a dedicated program, dedicated image data, and dedicated metadata, and the second storage area stores a common program, common image data, and common metadata (see FIG. 16 ). When the new cartridge 1 is connected to the new game device 50, the common program is read and game processing for a predetermined game, for example, is performed. Similarly, when the new cartridge 1 is connected to the old game device 70, the common program is read and similar game processing is performed. When the new cartridge 1 is connected to the new game device 50 and a predetermined condition is met (for example, when a transition is made to a specific scene), the new game device 50 reads the dedicated program from the new cartridge 1 and executes the dedicated program. This makes it possible to execute a dedicated program that takes advantage of the capabilities of the new game device 50 while reducing the amount of data stored in the storage medium 11 of the new cartridge 1.

[0240] In another embodiment, the new cartridge 1 is configured as a dedicated cartridge (see FIG. 17 ). In this case, a first application program, first image data, and first metadata are stored in a first storage area of ​​the storage medium 11 as data for the new game device 50. A display program, second image data, and second metadata are stored in a second storage area of ​​the storage medium 11 as data for the old game device 70. The first application program is a game program that enables a predetermined game to be played on the new game device 50. The display program is a program for displaying to the old game device 70 that the game cannot be played on the old game device 70. Thus, when the new cartridge 1 is connected to the new game device 50, the predetermined game can be played, and when the new cartridge 1 is connected to the old game device 70, a message indicating that the game cannot be played can be displayed.

[0241] Furthermore, the new cartridge 1 of the above embodiment has right-side notches 21 and 22 at one end in the second direction perpendicular to the first direction, which is the insertion / removal direction of the slot of the game device. The old cartridge 7 has substantially the same shape and size as the new cartridge 1, and has the right-side notch 21 but not the right-side notch 22 at one end in the second direction. Furthermore, an identification terminal P17 is provided inside the first slot 51 of the new game device 50 and is accommodated in the space formed by the right-side notch 22 when the new cartridge 1 is inserted. When the new cartridge 1 is inserted into the first slot 51, the identification terminal P17 does not contact the terminal 512. However, when the old cartridge 7 is inserted into the first slot 51, a portion of the housing of the old cartridge 7 contacts the identification terminal P17, and the identification terminal P17 contacts the terminal 512. This allows the new game device 50 to distinguish whether a new cartridge 1 or an old cartridge 7 has been connected.

[0242] Furthermore, the right-side cutout 22 is formed in a substantially L-shape when viewed from the bottom of the new cartridge 1. This ensures the strength of the housing of the new cartridge 1 even when the right-side cutout 22 is provided, and also facilitates the manufacture of the housing of the new cartridge 1. For example, compared to when the right-side cutout 22 is formed in an inverted C-shape when viewed from the bottom, rather than in a shape formed by cutting out a corner of the housing (compared to when the right-side cutout 22 is formed in a recessed shape in the negative x-axis direction from the center, rather than from the end in the z-axis direction, on the right side of the housing), when the right-side cutout 22 is formed in a substantially L-shape, the cartridge can be more easily inserted. That is, when the right-side cutout 22 is formed in a substantially L-shape with an open front side, as shown in FIG. 1( e), the L-shape can be easily aligned with the wall 515 of the slot, facilitating insertion of the cartridge into the slot. Furthermore, when the right-side cutout 22 is formed in a substantially L-shape, it is easier to remove the cartridge from the mold during manufacturing.

[0243] Furthermore, the width X2 of the right cutout 22 is configured to be wider than the width X1 of the right cutout 21. Furthermore, the right cutout 21 is formed to extend in the insertion direction (negative y-axis direction) to near the lower ends of the multiple terminals T, and the right cutout 22 is formed to extend from the lower end of the right cutout 21 in the insertion direction of the new cartridge 1. This ensures the strength of the housing more than, for example, when the entire right cutouts 21 and 22 have the width X2, and makes it possible to provide the right cutout 22 that enables the new game device 50 to identify the type of cartridge.

[0244] Furthermore, the identification terminal P17 is formed to protrude from the side surface of the first slot 51 in the left-right direction (x-axis direction) of the first slot 51, and the right cutout 22 has a width sufficient to accommodate the identification terminal P17. This allows the depth (length in the z-axis direction) of the right cutout 22 to be reduced, thereby ensuring the strength of the housing of the new cartridge 1. For example, if the identification terminal P17 were formed to extend in the thickness direction (z-axis direction) from the front or back surface of the first slot 51, the right cutout 22 to accommodate the identification terminal P17 would need to be deep enough. In this case, the strength of the housing in the area where the right cutout 22 is provided would be reduced. However, in this embodiment, because the identification terminal P17 protrudes in the left-right direction of the new cartridge 1, the depth of the right cutout 22 can be reduced, thereby ensuring the strength of the housing.

[0245] Furthermore, when an old cartridge 7 is inserted into the first slot 51, the detection terminal P1 on the game device comes into contact with the detection terminal T1 on the cartridge after the identification terminal P17 comes into contact with the terminal 512. This allows the new game device 50 to immediately perform processing according to the type of cartridge connected after detecting the connection, and to quickly perform processing such as reading data after connection.

[0246] (Modifications) The configuration, shape, etc. of the new cartridge 1 are not limited to those described above, and the following modifications may be made.

[0247] For example, in the above embodiment, the new cartridge 1 has normal firmware and compatible firmware, but in other embodiments, as shown in FIG. 42, the new cartridge 1 may have one common firmware.

[0248] FIG. 42 shows the configuration of the control unit 12 in the new cartridge 1 according to the first modification. The common firmware may be stored in the storage medium 11. In this modification, the common firmware is activated whether the cartridge 1 is connected to the new game device 50 or the old game device 70. When the cartridge 1 is connected to the new game device 50, signals conforming to the first standard are processed using the first-standard circuit 121, and communication between the cartridge 1 and the new game device 50 is based on the first standard. When the cartridge 1 is connected to the old game device 70, signals conforming to the second standard are processed using the second-standard circuit 122, and communication between the cartridge 1 and the old game device 70 is based on the second standard. Whether to process signals conforming to the first standard using the first-standard circuit 121 or signals conforming to the second standard using the second-standard circuit 122 may be determined when the new cartridge 1 is connected to the game device. For example, it may be determined whether to use the first standard circuit 121 or the second standard circuit 122 based on the voltage value at terminal P2 when new cartridge 1 is connected to the game device.

[0249] Furthermore, the shape of the housing of the new cartridge 1 is not limited to the above. Figure 43 is a view showing a new cartridge 1 according to a second modified example. Figure 44 is a view showing a new cartridge 1 according to a third modified example. Figure 45 is a view showing a new cartridge 1 according to a fourth modified example. Figure 46 is a view showing a new cartridge 1 according to a fifth modified example. Figure 47 is a view showing a new cartridge 1 according to a sixth modified example.

[0250] For example, in the above embodiment, the right-side cutout 21, which functions as a rail when inserting the new cartridge 1 into the slot, is formed to extend to the upper end of the new cartridge 1. However, as shown in Figure 43, the right-side cutout 21 may be formed from the third position P_Y3, which is the upper end of the right-side cutout 22, to a fourth position P_Y4 below the upper end of the new cartridge 1. In the range from the fourth position P_Y4 to the upper end in the y-axis direction, and in the range from the right end in the x-axis direction to a distance X1 to the left, the entire front housing 2 and the rear housing 3 may be cut out, and no housing may be formed. In other words, the rail does not necessarily have to be provided from the upper end to the lower end in the y-axis direction, but may be provided from the fourth position P_Y4 below the upper end in the y-axis direction.

[0251] Furthermore, the shape and length of the right-side notch 21 are not limited to those shown in the figure, and may be any, as long as it functions as a rail when inserting the new cartridge 1 into the slot of the new game device 50 or the old game device 70.

[0252] Furthermore, the shape of the right-side cutout 22 is not limited to that described above. For example, as shown in FIG. 44, the left end of the right-side cutout 22 may be formed in a straight line. That is, the right-side cutout 22 may have a constant width X2 from the first position P_Y1 to the third position P_Y3 in the y-axis direction, and may be formed in an R-shape from the first position P_Y1 to its bottom end. Furthermore, the four corners of the new cartridge 1 may not be formed in an R-shape, and the right-side cutout 22 may have a constant width X2 from its top end to its bottom end.

[0253] 45, the right-side cutout 22 need not be shaped like a partial cutout of the front housing 2, but may be shaped like a cutout of the entire front housing 2 and the entire rear housing 3. In other words, the entire front housing 2 and the entire rear housing 3 may be cut out in the range below the third position P_Y3 (the lower end of the right-side cutout 21) in the y-axis direction and in the range from the right end in the x-axis direction to a distance X2 to the left, and no housing may be formed. Even if the right-side cutout 22 has the shape shown in FIG. 45, when the cartridge is inserted into the slot of the new game device 50, terminal P17 does not come into contact with the cartridge housing, and terminal P17 does not come into contact with terminal 512.

[0254] 46, the right-side cutout 22 may be formed to extend from the top to the bottom of the new cartridge 1. In this case, like the right-side cutout 21, the right-side cutout 22 also functions as a guide when inserting the new cartridge 1 into the slot of the new game device 50 or the old game device 70. The right-side cutout 22 may function as a rail by coming into contact with a wall 515 provided in the slot when the new cartridge 1 is inserted into the slot of the new game device 50 or the old game device 70, or may be formed so that it does not come into contact with the wall 515 when inserted into the slot (does not function as a rail). The right-side cutout 22 has a width X2 and, similar to FIG. 27, forms a space to accommodate the terminal P17 of the new game device 50. Therefore, when the new cartridge 1 having the shape shown in FIG. 46 is inserted into the first slot 51 of the new game device 50, the terminal P17 does not come into contact with the terminal 512, and the new game device 50 detects the connection of the new cartridge 1.

[0255] 47 , the right-side cutout 22 may not have a portion with a constant width, and may be formed obliquely with respect to the y-axis from its lower end to the third position P_Y3. That is, the right-side cutout 22 may be formed in a tapered shape from the first position P_Y1 to the third position P_Y3, and may be formed in an R-shape from the first position P_Y1 to the lower end.

[0256] The shape of the housing of the new cartridge 1 may be any combination of the shapes shown in Figures 43 to 47. For example, as shown in Figure 43, the right-side cutout 21, which functions as a rail when inserting the new cartridge 1 into the slot, may be provided from the top end of the new cartridge 1 down to a fourth position P_Y4, and the shape of the right-side cutout 22 may be as shown in Figure 44. Alternatively, the left end of the right-side cutout 22 may be formed in a straight line as shown in Figure 44, and the front housing 2 and the rear housing 3 may be cut out entirely as shown in Figure 45.

[0257] Furthermore, in the above embodiment, the new game device 50 distinguishes whether the old cartridge 7 or the new cartridge 1 has been connected by the terminal P17 provided inside the first slot 51 coming into contact with the housing of the old cartridge 7. The method of distinguishing whether the old cartridge 7 or the new cartridge 1 has been connected is not limited to this, and other methods may be used. Below, other distinguishing methods of distinguishing whether the old cartridge 7 or the new cartridge 1 has been connected will be described with reference to Figures 48 to 59.

[0258] Figure 48 is a diagram showing another identification method, showing a new cartridge 1 connected to a new game device 50 according to the seventh modified example. Figure 49 is a diagram showing another identification method, showing a new game device 50 according to the seventh modified example, showing an old cartridge 7 connected to the new game device 50 according to the seventh modified example.

[0259] As shown in FIG. 48 , in the new cartridge 1 according to the seventh modification, the long terminal T15 (ground terminal) arranged across the upper and lower regions of the terminal arrangement region is replaced with a short terminal T15' (ground terminal) arranged in the upper region. An identification terminal T18 is provided in the lower region below the short terminal T15'. The lower end of the identification terminal T18 is located lower than the lower end of the detection terminal T1. An identification terminal P18 is provided inside the first slot 51 of the new game device 50 according to the seventh modification, at a position overlapping with the identification terminal T18. When the new cartridge 1 is connected to the first slot 51 of the new game device 50, the ground terminal P15 comes into contact with the ground terminal T15', and the identification terminal T18 comes into contact with the identification terminal P18. On the other hand, as shown in Figure 49, when an old cartridge 7 is connected to a new game device 50 according to the seventh modification, the ground terminal P15 comes into contact with the ground terminal T15, and the identification terminal P18 comes into contact with the ground terminal T15. The new game device 50 according to the seventh modification can determine whether a new cartridge 1 or an old cartridge 7 is connected based on the state of the identification terminal P18. Note that the positions of the ground terminal P15 and the identification terminal P18 may be reversed in the y-axis direction, and the positions of the ground terminal T15' and the identification terminal T18 may also be reversed in the y-axis direction. That is, the identification terminal P18 and the identification terminal T18 may be located in the upper region, and the ground terminal P15 and the ground terminal T15' may be located in the lower region.

[0260] Figure 50 shows another identification method, and is a diagram showing the new cartridge 1 connected to the new game device 50 according to the eighth modified example. Figure 51 shows another identification method, and is a diagram showing the old cartridge 7 connected to the new game device 50 according to the eighth modified example.

[0261] As shown in FIG. 50 , in the new cartridge 1 according to the eighth modification, the long terminals T7 (power terminals) arranged across the upper and lower regions of the terminal arrangement area are replaced with short terminals T7' (power terminals) arranged in the upper region. An identification terminal T18 is provided in the lower region below the short terminals T7'. The lower end of the identification terminal T18 is located lower than the lower end of the detection terminal T1. An identification terminal P18 is provided inside the first slot 51 of the new game device 50 according to the eighth modification, at a position overlapping with the identification terminal T18. When the new cartridge 1 is connected to the first slot 51 of the new game device 50, the power terminal P7 comes into contact with the power terminal T7', and the identification terminal P18 comes into contact with the identification terminal T18. On the other hand, as shown in Figure 51, when an old cartridge 7 is connected to a new game device 50 according to the eighth modified example, the power terminal P7 comes into contact with the power terminal T7, and the identification terminal P18 comes into contact with the power terminal T7. The new game device 50 according to the eighth modified example can determine whether a new cartridge 1 or an old cartridge 7 is connected based on the state of the identification terminal P18. Note that the positions of the power terminal P7 and the identification terminal P18 in the y-axis direction may be reversed, and the positions of the power terminal T7' and the identification terminal T18 may also be reversed in the y-axis direction. That is, the identification terminal P18 and the identification terminal T18 may be located in the upper region, and the power terminal P7 and the power terminal T7' may be located in the lower region.

[0262] Although not shown, the power supply terminal T10 may be replaced with a short terminal T10' instead of the power supply terminal T7. In this case, an identification terminal T18 is provided in the lower area below the short terminal T10'. When the new cartridge 1 is connected to the first slot 51 of the new game device 50, the power supply terminal P10 and the power supply terminal T10' come into contact, and the identification terminal P18 and the identification terminal T18 come into contact. On the other hand, when the old cartridge 7 is connected to the new game device 50, the power supply terminal P10 and the power supply terminal T10 come into contact, and the identification terminal P18 and the power supply terminal T10 come into contact. In this case, as in the above, the positions of the power supply terminal P10 and the identification terminal P18 in the y-axis direction may be reversed, and the positions of the power supply terminal T10' and the identification terminal T18 may also be reversed.

On the other hand, as shown in FIG. 57 , when the old cartridge 7 is connected to the new game device 50 according to the eleventh modification, the power terminals P7 and T7 come into contact, and the identification terminal P18 and T7 come into contact. The new game device 50 according to the eleventh modification can determine whether a new cartridge 1 or an old cartridge 7 has been connected based on the state of the identification terminal P18. The positions of the power supply terminal P7 and the identification terminal P18 in the y-axis direction may be reversed, and the power supply terminal T7' may be provided in the lower region. In other words, the identification terminal P18 may be located in the upper region, and the power supply terminals P7 and T7' may be located in the lower region.

[0269] Figure 58 is a diagram showing another identification method, showing a new cartridge 1 connected to a new game device 50 according to the twelfth modified example. Figure 59 is a diagram showing another identification method, showing a new game device 50 according to the twelfth modified example with an old cartridge 7 connected.

[0270] As shown in FIG. 58 , in the twelfth modification, the power supply terminal T10 may be replaced with a short terminal T10′ instead of the power supply terminal T7. An identification terminal P18 is provided inside the first slot 51 at a position overlapping the lower region below the short terminal T10′. When a new cartridge 1 is connected to the first slot 51 of the new game device 50, the power supply terminal P10 and the power supply terminal T10′ come into contact, but the identification terminal T18 and the short terminal T10′ do not come into contact. On the other hand, when an old cartridge 7 is connected to the new game device 50 according to the twelfth modification, the power supply terminal P10 and the power supply terminal T10 come into contact, and the identification terminal P18 and the power supply terminal T10 also come into contact. Note that the positions of the power supply terminal P10 and the identification terminal P18 in the y-axis direction may be reversed. That is, the identification terminal P18 may be located in the upper region, and the power supply terminal P10 and the power supply terminal T10′ may be located in the lower region.

[0271] In the above embodiment, the new cartridge 1 is supplied with power from the new game device 50 or the old game device 70, but the new cartridge 1 may have a built-in power source, or may be supplied with power from another device. In this case, the new cartridge 1 does not need to have the power terminals T7 and T10 for supplying power from the new game device 50 or the old game device 70.

[0272] In the above embodiment, the new cartridge 1 is provided with a right-side notch 22, and the first slot 51 of the new game device 50 is provided with a switch (terminal P17) that changes its on / off state when a part of the housing of the old cartridge 7 comes into contact with the switch when the old cartridge 7 is inserted. The switch (terminal P17) is configured so that its state does not change when the new cartridge 1 is inserted. That is, the information processing device (new game device) according to the above embodiment includes a first slot into which a first cartridge and a second cartridge that is insertable into and removable from a second slot of a second information processing device can be inserted. The information processing device also includes a switch that is provided in the first slot and changes its on / off state when a part of the housing of the second cartridge comes into contact with the switch when the second cartridge is inserted into the first slot, and that does not change its state when the first cartridge is inserted; a circuit that determines the on / off state of the switch; and a detection terminal that is provided in the first slot and detects whether the first cartridge or the second cartridge is connected. The information processing device is configured such that when the second cartridge is inserted into the first slot, the state of the switch changes and then the detection terminal comes into contact with the detection terminal of the second cartridge, and when the first cartridge is inserted into the first slot, the state of the switch does not change and the detection terminal comes into contact with the detection terminal of the first cartridge.

[0273] In an information processing device according to another embodiment, the switch may be configured to contact the housing of the new cartridge 1 but not to contact the housing of the old cartridge 7. That is, an information processing device according to another embodiment may include: a first slot into which the first cartridge and the second cartridge are insertably / removably received; a switch provided in the first slot, the switch changing its on / off state when a part of the housing of the first cartridge comes into contact with the switch when the first cartridge is accommodated in the first slot and the switch does not change its state when the second cartridge is accommodated in the first slot; a circuit that determines the on / off state of the switch; and a detection terminal provided in the first slot that detects connection of the first cartridge or the second cartridge, the detection terminal being configured so that when the first cartridge is inserted into the first slot, the detection terminal comes into contact with the detection terminal of the first cartridge after the state of the switch changes; and when the second cartridge is inserted into the first slot, the detection terminal comes into contact with the detection terminal of the second cartridge without changing the state of the switch.

[0274] Furthermore, in the above embodiment, the storage medium 11 of the new cartridge 1 is fixed to the new cartridge 1. However, in other embodiments, the storage medium 11 of the new cartridge 1 may be detachably connected to the new cartridge 1. For example, the storage medium 11 detachably attached to the new cartridge 1 may be a storage medium based on a third standard different from the first and second standards. For example, the storage medium 11 detachably attached to the new cartridge 1 may be a storage medium conforming to the SD standard. FIG. 60 shows a modified example of the new cartridge 1, a cartridge equipped with a detachable storage medium 11. As shown in FIG. 60, the new cartridge 1 includes multiple terminals connected to multiple terminals of the detachable storage medium 11 and a converter 13 that converts signals conforming to the third standard into signals conforming to the first or second standard. The controller 12 of the new cartridge 1 controls the converter 13 depending on the game device to which it is connected. Specifically, when the new cartridge 1 is connected to the new game device 50, communication between the new cartridge 1 and the new game device 50 is based on the first standard, and the converter 13 converts signals conforming to the first standard into a third standard to communicate with the removable storage medium 11. When the new cartridge 1 is connected to the old game device 70, communication between the new cartridge 1 and the old game device 70 is based on the second standard, and the converter 13 converts signals conforming to the second standard into a third standard to communicate with the removable storage medium 11. The converter may be included in the control unit. That is, an integrated circuit constituting the control unit may have a conversion function for converting between the first standard and the second standard. The removable storage medium 11 may be a storage medium conforming to either the first standard or the second standard. In this case, the new cartridge 1 may not have the converter 13, and the control unit 12 may process signals according to the connected game device.

[0275] In another embodiment, the application program (e.g., a game program) is loaded into the new game device 50 and executed only when the new cartridge 1 is inserted into the new game device 50; when the new cartridge 1 is inserted into the old game device 70, the application program is not executed, and the warning or error message based on the program (e.g., a display program) stored in the new cartridge 1 is not displayed. Specifically, the control unit 12 of the new cartridge 1 may be provided with a circuit for the first standard shown in FIG. 11 , but not with a circuit for the second standard 122. In this case, the storage medium 11 may be configured to store programs and data for the new game device 50, but not programs and data for the old game device. In this case, communication between the control unit 12 and the storage medium 11 may be performed based on the first standard, not the second standard. Alternatively, in another embodiment, the control unit 12 of the new cartridge 1 may be provided with a first standard circuit 121 and a second standard circuit 122 as shown in FIG. 11, while the storage medium 11 may store programs and data for the new game device 50, but not programs and data for the old game device 70.

[0276] Similarly, in the modification shown in FIG. 60 , the application program (e.g., a game program) is loaded into the new game device 50 and executed only when the new cartridge 1 is inserted into the new game device 50; when the new cartridge 1 is inserted into the old game device 70, the application program is not executed, and the warning or error display based on the program (e.g., a display program) stored in the new cartridge 1 may not be displayed. Specifically, the control unit 12 may be provided with a circuit 121 for the first standard, but not with a circuit 122 for the second standard. Alternatively, the storage medium 11 may be configured to store programs and data for the new game device 50, but not for the old game device 70. In this case, communication between the control unit 12 and the conversion unit 13 is based on the first standard. The conversion unit 13 may be capable of bidirectional or unidirectional conversion between signals conforming to the first standard and signals conforming to the third standard, but may not be capable of conversion between signals conforming to the second standard and signals conforming to the third standard. Furthermore, the control unit 12 may be provided with a first standard circuit 121 and a second standard circuit 122, while the storage medium 11 may store programs and data for the new game device 50, but not for the old game device 70. Note that the new cartridge according to this modified example may be configured so that it can be physically inserted only into the new game device 50, and cannot be inserted into the old game device 70.

[0277] The new cartridge may be connectable to a plurality of storage media, and may be switchable between any of the plurality of storage media, and may be capable of writing and reading data to and from any of the plurality of storage media.

[0278] Furthermore, the configurations according to the above-described embodiments and their modifications can be combined in any manner as long as they are not inconsistent with each other. Furthermore, the above is merely an example of the present invention, and various other improvements and modifications may be made thereto.
